Within this world, there was once a grand city called Orario, the city of adventurers. Numerous mortals came all over to fulfill their desires for fame and fortune. Being built over a massive dungeon crawling with numerous monsters that spawn daily and threaten the peace of the people. Left unchecked will no doubt bring upon chaos and despair if not for the efforts of the past heroes who held back the monster's waves.

With the descent of the Gods from Tenkai, sealing of the dungeon and granting mortals the power of the falna, granted new hope for the mortals. With falna increasing by getting experience (or known as excelia) the mortals gain new abilities, fighting back against the monsters and exploring the dungeon, granting them the title of adventurers.

So long as these adventurers and their Gods remain in Orario, there would at least be a form of peace for the rest of the mortals outside of Orario and to other kingdoms.

But one day the city had vanished, with all of the residents, adventurers and even the Gods who were inside of the city. Including the entirety of the top portion of the Tower of Babel. Without Oranous keeping the dungeon in line, the dungeon took this opportunity and released its full onslaught of monsters to the surface without anyone holding it back. Chaos and Destruction was eminent, as the Gods and adventurers outside of Orario could not stand a chance against them.

Several Gods and Goddesses witnessing the destruction and death caused by the dungeon, started to disregard the rule that they had placed on themselves when they descended from Tenkai.

The sealing of their Arcanum.

Perhaps these Gods and Goddesses did it out of love for their familia and for the mortals, or maybe even out of necessity to ensure their own safety from the rampaging monsters.

But there will be those who only did it, as their form of entertainment would be gone, as it is ending their vacation and increasing their workload when they get back to Tenkai, which is something they don't want to happen.

But all of the Gods and Goddesses that descended from Tenkai, can all agree on one thing. That the dungeon needed to be sealed once more, soon a group of Gods and their familias volunteered to march to the unsealed dungeon.

However something unprecedented happened.

The moment they tried to unseal their Arcanum, the Gods and Goddesses felt it.

They discovered that a foreign power would start sealing away their Arcanums once again.

It was realized that this foreign power would only begin sealing a God's Arcanum when the Gods themselves tried unsealing it to fight against the monsters themselves.

News of this was slow as there was no proper communication network between the Gods who stayed behind and to those who went and tried sealing the dungeon.

By then several of the volunteered Gods and their familias arrived at the unsealed dungeon and tried sealing it once again, only for them to have realized it too late. On that day several pillars of light ascended to Tenkai signaling to the world that multiple Gods have perished. Those familias that have lost their Gods were then slaughtered by the monsters as they no longer had the ability to fight them.

This brought more panic among the chaos as the Gods themselves are now powerless against the spawns of the dungeon.

Creating a new age of darkness upon the world.

However in these times of despair and chaos, a torch has lightened among the mortals.

As for the Gods have witnessed it numerous times and cheered upon it during their times in heaven before their descent.

It was the signal of the rise of a Hero

The one who shall bring upon the new hope upon the world and the one who shall give the rise to all others after him.

The one who will create new legends and myths that shall forever be ingrained upon the land and remembered by the Gods in heaven.

With the alias of White Dawn

Being the Captain of the Astrea Familia

and King of Dragon Tail City.

He is

Bell Cranel

x-x-x-x-x

Sitting in his office, Bell Cranel was looking at a document, with a quill on hand and a thoughtful face as he reads the document carefully, understanding what's the context is, he signed his name on it and placing it on the pile of signed documents on his right before grabbing another document from the other pile of unsigned documents on his left.

Tick…Tick…Tick…Tick

Hearing the rhythm ticking sounds, Bell stopped to look up to see the clock on the wall with its hands pointing at the current time.

"So it's almost lunch time huh, guess I better end it here then, or else they would scold me again for overworking myself, haha" he thought to himself

With a small chuckle and smile looking at the clock he places his quill down as he remembers the numerous times that his wives and familia executives had scolded him for overworking his mind and body.

After all, if one compares the workload of a familia captain and that of a king of a growing nation, it would be something like comparing a bucket full of water to that of a water filled pool. It's a weird comparison but it is accurate to his current workload.

After that comparison between his past and current workloads, Bell reached out to his shirt breast pocket on his left and grabbed a small piece of paper. Opening it up, it is revealed that it is his schedule for the day.

Normally he would have a Famlia Executive with him who acts as his secretary (and also as a maid for some reason?) to report about his current schedule, but he sent her away to investigate some disturbing rumors regarding an old dwarven fortress up north from here.

Looking at his schedule "Hmm after lunch with my family, I need to contact the familia executives to hear their daily reports if there has been any changes or information that has been found recently"

Being the captain of the still mainly female familia (being the only guy) it's his duty to gather information from what can be found by his familia, in order to prepare his army and familia for what is to come especially from them.

His familia has multiple sub-bases all over, with dragon tail city being the main base of the familia.

Some were even located in the far east, as well as in the Alf's forest, though granted that he had to make a deal with the Elven Empress, that the base would have to be operated solely by elves, which he was fine with, and of course the most important sub-base of all.

The one located in the Mother Labyrinth.

With that single thought, by reflex Bell started to feel a slow rage and frustration build up within him, as memories began flooding his mind of that dreadful place slowly looking at his calendar on his desk, reminding him of what has happened in the past

Formerly known as the Orario's Dungeon, it was renamed into the Mother Labyrinth after the disappearance of Orario City and the rise of them.

With the destruction and death it caused during the first and second year of Orario's absence, it needed a new name.

"At first even Astrea and the other Gods didn't know what had caused the disappearance of Orario or the sudden changes that have happened around the world." Bell thought

Remembering the conversations that he had with his Goddess and other Gods he met, they all told him the same thing, that they also don't know the exact reason for the events that have unfolded at first.

However, it was later on that the Gods and Goddesses soon had a revelation, and set up a place to meet during the chaos to discuss it.

It was confirmed that the power that sealed the Gods Arcanum and the energy that Gods felt when Orario had disappeared, was the same thing.

Astrea had told him and to the familia on what she and the other Gods have found, and asked to keep it a secret from the public until the suspicions have been confirmed.

Bell soon slowly started relaxing his expression, as he saw no point on keeping his current expression at an old memory and began burying it deep in his mind once again, sighing at his current mood

*sigh* "Calm down Cranel, there's no point being mad at an old memory of the past, what's important now is to focus what is a-"

Before he could complete his sentence his train of thought stopped as something caught his attention at the corner of his eye, it was a framed portrait on his desk.

With a sad smile he stared at a small framed painted portrait on his desk with full attention.

It depicted five individuals smiling in front of a building. It was his original familia, the Hestia Familia.

Reminiscing about his time in Orario, remembering how he was rejected by every familia within the city and perhaps by Faith or coincidence, met Hestia-sama in an alleyway and became her first familia member.

Hestia-sama, the person who gave him the chance to become a hero of his dreams, and someone who he truly respects and adores.

As his time in Orario continues, the Hestia Familia slowly grew with new members joining the familia, though mostly because of special circumstances

Liliruca Arde the Prum, the supporter of the familia and even the brains in several of their familia operations.

Welf Crozzo, his best friend and big brother figure, being the main blacksmith of the familia and could always count on him to have his opinion.

Yamato Mikoto, a good friend and a reliable swordswoman, is always there to have his back.

Sanjouno Haruhime a Renard, having unique and powerful magic in his opinion, and shares the same love for hero stories

Recalling the various memories that he had with his old familia, Bell began to also recall the events and friends that he had made during his time within the walls of Orario.

In the guild Eina Tulle his guild advisor, she was the one who always provided advice during his time in Orario's dungeon, crediting his entire survival in the dungeon to her.

At the Hostess of Fertility, remembering the food that he enjoyed and the people that he met there, such as Syr Flova, who always gave him….well…..edible lunches?

Besides the questionable lunches she made for him, she was always there to support him in his endeavors.

There was also Ryuu Lion the elf, she helped in his training to become stronger holding high esteem for her, as she always provided him with important lessons.

The Miach and Takemikazuchi Familias, important allies and friends that he had made.

More memories began flooding into his mind, recalling the past events and faces of the people he had met when he was in Orario striving to become a hero.

Soon a particular memory caught his attention as it stood out from the rest.

Depicting a beautiful and strong female swordswoman with golden hair and eyes

If anyone could read his thoughts and had lived in Oriaro and saw this person, they would instantly know who this is.

"Ais" bell mutters in a quiet voice to himself

His Crush and Inspiration

Remembering the level 6 Sword Princess from the Loki Familia, she has always created a sense of awe and admiration for him.

That's why he fell in love with her, when she saved him from the minotaur on the 5th floor of the dungeon back then.

Becoming his goal to not only stand beside her, but perhaps even confess to her when the time comes.

However in the end, it only became a one sided love since he never confessed to her, as she too had disappeared on that fateful day.

Though he was able to move on from it, he won't lie to himself that he still has some regret for not properly making it up to Ais after the whole Xeno Fiasco that has happened between them.

Especially in the heated encounter when Wiene was together with him.

Granted that they both made up with each other on Orario's walls back then, but in his opinion he felt like he could've done better.

After recalling the memories he had made during his time in Orario, Bell couldn't help himself but let out a bitter laugh and looked down on himself.

"Heh" Bell thought to himself "I should really stop this habit of mine when I work, it's good and all to remember them, but doing it almost everyday now can cause issues to my work" scratching his cheek with a small smile.

Realizing that an old habit that he developed after Orario's disappearance has once again resurfaced, he couldn't help but complain to himself.

Muttering "old habits die hard I guess" as he remembers what his wives had discussed with him during their wedding night.

Wedding Night Flashback

"Bell remember that the past will always remain in the past, all we can do now is focused on what is ahead of us" a woman telling him as she sat beside him on the bed on his right

"She's right, so you should stop blaming yourself for not being there with your friends when Orario disappeared" a second woman told him as she sat down on his left.

*sigh* "I know, it's just that…would they really be…happy for me…that I moved on?" Bell questions the two women sitting with him with a sad smile

"Bell, we all know that they want you to be happy" the woman said on the right, linking her arm with his and placing her head down on his shoulder with a smile.

"Hehe, from what you tell me about your friends, I'm pretty sure that they would get mad at you for preventing yourself from being happy" the woman giggled on his left and mimicked the same action that the woman on the right has done.

Hearing the confirmation from both women, Bell let out a genuine smile as he himself knew that his friends would want him to be happy and only wanted confirmation from the women that he loves.

"Thank you...Both of you" Bell said to both of the women

"Hehe, it's no issue your our husband now after all" the woman on the right giggled as she let out a smile.

"She's right, all we want is the best for you" the woman on the left side said with strong affirmation of her words.

Bell smiled at himself "heh, truly I am thankful for having such wonderful women at my side" bell thought to himself. But before he could say anything else, he was interrupted as he was strongly pushed down onto the bed.

"Eh" he could only mutter while laying down as he can see the two woman suddenly standing up and facing him

"Now with that out of the way" the woman on his right said as she slowly started stripping her wedding clothes off, showing off her white lingerie that highlights her voluptuous body.

"Shall we begin" said the woman on the left doing the same, showing off her black lingerie.

Both women then began crawling onto the bed, placing one hand on his chest and the other to his crotch, with a sultry voice and lustful look both women licked their lips as they looked straight onto the frightened rabbit.

"This Rabbit Feast" both of the women said

Seeing the hunger in their eyes, Bell himself knew that he would not be able to escape, so the only option left for Bell was…

"Oh Gods pls give me strength" Bell said in a quiet and pleading voice

To Pray

Wedding Night Flashback End

Remembering that night, Bell couldn't help but blush a bit, as it should have been one of the most intense nights he had with his wives, but comparing it to now….it seems tame in comparison.

Besides questioning if his sex life is healthy or not, Bell remembered what he had discussed with them. "The past will always remain in the past huh" he thought.

As he thought about it, he then realized that he spent too long thinking to himself regarding the past and that he should really start moving to meet with his family for lunch, unless he wants to incur the wrath of his wives

With that he lets out a short laugh and was about to stand up from his chair

Until

BAM!

Suddenly a sudden burst opening of the office door, Bell looking up to see it was a person adorning a full body armor suit with a design being a mix of white and silver with red lining around the armor with the exception of the helmet that had a dragon look design, the full body armor itself being quite similar in design to the first light armor that he ever got in his time of Orario and made by his friend Welf.

Of course the reason being was that He was the one who designed and commissioned it to be made, in order to Honor and remember his blacksmith friend.

Bell also remembers that this type of armor was only assigned to a single specific unit within his kingdom and are the guards of his family…the Silver Dragon Guards.

Walking towards the king and stopping only a few meters in front of his desk.

The Silver Dragon Guard immediately opened his helmet visor and kneeled to his King.

Normal procedures after all, as even though Bell still considers himself to be an adventurer most of the time, but to the people he is always their King.

Now usually this guard would get chewed out if anyone else was in the room with him, such as his generals, familia executives, advisors and even his wives, scolding the guard for not following the procedures or even knocking the door as this IS the King's office after all

Thankfully he was alone this time and he himself didn't really mind it

However, seeing the expression on the Silver Dragon Guard's face, a mixture of confusion, unsureness and worry gave him slight anxiety but didn't show it on his face and waited for what was to come from the royal guard's mouth.

"You may speak" Bell told to the silver dragon guard

Looking up, the guard faced his king "Your Majesty! We have an urgent report from the Occulus Communication Line from the construction site of the great wall surrounding the Mother Labyrinth!" The Silver Dragon Guard reported to his king

Hearing this Bell widened his eyes in horror, as the great wall was still under construction to incorporate repairs and new upgrades after the last attack from the Labyrinth.

Currently it can only hold off against monster parties and tides sent by the Mother Labyrinth, but if its a Monster Wave

Then that's a different story

"Could it be that a Monster Wave has broken through the Wall!" Bell shouted, thinking the worst might have happened.

He stood up with his hands still on his desk with a shocked and worried look. Immediately thinking of calling out his generals to tell them to rally up the troops while he and available Familia members will go ahead and gather upon the transfer gate for a transfer to the wall, so that they can hold back the monster tide until reinforcements from his kingdom and allies arrive. Luckily or rather thankfully, it wasn't none of that dreadful thought that he had.

"No your Majesty! The walls have not been breached!" The Silver Dragon Guard replied back immediately to clear the misunderstanding

Hearing that bell sighed in relief and immediately sat back down on his chair and looked at the guard with a serious expression.

"I see, then what is it?" Bell questioned the guard

The Silver Dragon Guard at first hesitated to reveal the contents of the report, but knowing his duty, the guard answered to his king.

"It's about the Mother Labyrinth your Majesty….it has been reported that….Orario has returned" the guard replied with some hesitation to the king's question

Hearing those words bell widens his eyes even more so than before with his mouth slowly gaping to the point where a fly can fly in by accident. He stared at the royal guard with an unmoving gaze and shocked look, only able to say a single word in this situation.

"...What?"

Orario, the city of adventurers that had disappeared with everyone that he knew and loved…has now returned….after 10 years.
