~~~~~~~~~~~~~~~~~~~~~~~DuellistTale~~~~~~~~~~~~~~~~~~~~~~~

Frisk cried out as they tripped on a tree root as they reached the top of Mt. Ebbot. They tripped and tumbled forwards, and fell straight into a dark hole. They checked their pockets. Nothing. Everything had fallen out. They checked their rucksack. Nothing. It had been torn and everything had fallen out. They fell downwards as they felt tears well up in their eyes. Was this it? Was this the sweet sweet embrace of death? The cold air rushed passed them as they fell and they saw a large mass of gold approaching. They clasped their hands together and prayed, waiting to go to heaven with their parents.

{If you know how the game is played, the skip to the next bold message}

In the world of the Underground, battles were held with card games. Each card had their own individual Attack (ATK) Points and their own Defence (DEF) points. These were Monster cards. The Duellist also had LifePoints (LP) that, when depleted all the way to zero, lost you the duel. There were also Spell cards and Trap cards. These had effects to either one or both players and when combined with Monster cards, could often win the duel. Duellists would summon monsters based on their Level. Cards that were level 1-4 could be summoned without any extra cards unless the card had Summoning Conditions. Monster cards with a level from 5-6 required 1 tribute, whilst monsters at level 7-8 required 2. Anything above that usually needed 3 tributes. Monsters could Attack each other, and monsters that were in Attack Position would be the ones to do so. When they attacked an opponents monster, the difference in ATK points was calculated and the loser took the Overlap damage in LP. However, monsters could also be played in Defence Position. If these monsters were attacked, the difference was between the ATK of the opponents monster, and the DEF of the monster being attacked. If the ATK was higher than the DEF, then the Defence Position monster would be destroyed, but no LP damage taken. However if the DEF was higher than the ATK, then the opponent would take the overlap in LP, but their monster would not be destroyed. Once someone got to 0 LP, they lost the duel. Most duels started on 8000 LP.

{Here starts the differences from Yu-Gi-Oh}

If they lost, then the loser would be at the mercy of the winner. The winner had two options. [SPARE] or [KILL]. Sparing an opponent would mean they stayed alive, and all that was lost was their pride. However if the opponent chose kill...well...lets just say that the opposing monster was not going to like what happened next.

Many monsters had a deck based on their personality and species. For example, a monster like Temmie would most likely have a Beast deck, but one that had crazy effects and around average ATK and DEF points. Overall it would not win them the Duel if they got seriously challenged.

In addition, monsters had their Soul Card which was usually their strongest monster card in their deck. An example of this was the card Frightfur Wolf. This was Temmie's Soul Card and basically the one that she relied on the most. This card was also a representation of their soul, and so knowing someone's Soul Card was a show of trust.

Frisk shook their head, trying to clear the black spots that danced in their vision. They shakily stood up and looked around. They realised that they were on a bed of golden flowers and that they were in a room with just one exit. The corridor to the left of them. They looked up and could make out a pinprick of light in the distance. They felt tears well up in their eyes but they wiped them away. They were strong. They could survive. They slowly made their way down the corridor and into the next room.

When they entered the room they saw a single golden flower in a sea of grass. However, this flower looked...different...Frisk jumped back as the flower moved and turned towards her. Frisk walked closer to the flower and saw that it had a FACE! Their eyes widened and they backed up a bit before hearing the flower speak.

"Howdy! I'm Flowey! Flowey the Flower! Golly, you must be so confused!" The flower spoke with such happiness that Frisk found themselves starting to like the flower. Flowey spoke again.

"I guess that means its up to me to explain everything to you! Shall we have a practice duel whilst I explain?" Frisk nodded eagerly and sat down in front of Flowey. A deck of cards appeared in front of the flower and it waited expectantly for Frisk to produce their Deck of cards. Upon seeing the non-existance of such a deck though, Flowey's smile started to turn a bit more malicious.

"Do you have a Deck Human?" Flowey asked Frisk and Frisk mutely shook their head. Flowey started to laugh.

"No deck? I guess that means I can attack your life points directly! Also, it means you can't stop me when I disobey the rules!" Flowey grinned evilly and declared loudly:

"I summon my Black Rose Dragon in Attack Position!" A card brought itself from a smaller deck and flipped itself face up, giving a clear view of the Synchro Card that Flowey summoned without tuners! The dragon appeared on the battlefield that a had been created when Flowey dragged them into a [DUEL].

"I also equip Axe of Despair! This means that my dragon is on 3400 ATK! Now my dragon, Attack!"

The dragon in front of Frisk opened it's jaw and roared, and razor sharp rose petals hit Frisk's body and they cried out in pain. They also saw a little metre next to them flash briefly and go down from 8000 LP to 4600 LP. Their eyes widened and they whimpered at Flowey who was laughing manically!

"I now draw a card and play Pot of Greed! I draw two more cards and guess what! I equip them to my Black Rose Dragon!" Frisk saw the metre by Flowey's monster go up from 3400 ATK to 5400 ATK.

"Don't you get it human?! In this world, Its Defeat or Be Defeated!" Flowey laughed again and opened his mouth once more.

"Now, my dragon, Atta-!" Flowey was cut off as a voice declared

"You activated my trap card! Magic Cylinder!" The voice called.

"WHAT!" Flowey raged as he took the 5400 LP, bringing him down to 2600 LP.

"Begone!" The voice called as a figure emerged from the ruined buildings.

"Fine!" Flowey snarled and disappeared into the ground. A large goat like creature emerged from the building and headed over to Frisk.

"Such a Foul Creature, torturing a poor, innocent youth. Are you all right my child? I am Toriel, caretaker of the Ruins." Frisk nodded slowly to show that yes, they were all right now that Flowey was gone.

"Come with me child, I will take care of you" Toriel smiled and led them through the Ruins, letting them try some of the puzzles that were there.

~~~~~~~~~~~~~~~~~~~~~~~DuellistTale~~~~~~~~~~~~~~~~~~~~~~~

Finally they reached a room and Toriel looked down, a sad expression on her Face.

"Forgive me my child, but I have to go and get some things. Please wait here whilst I go. Do you have a phone?" Upon the shake of Frisk's head, Toriel brought out a spare phone and gave it to them. It only had Toriel's number on it. Toriel smiled and left them in the room. Frisk sat down against the wall and started to ponder what was going on. There were monsters and they fought each other with a card game. There was something called LP and ATK...They pondered over the game and decided that they needed to learn how to play in order to defend themselves.

After 20 minutes of waiting, Frisk saw a small glint in the corner of their eye. They put down the rocks that they were drawing with and headed over to it. The object was star shaped and a bright yellow. They reached out their hand and touched it. Suddenly, two boxes appeared in front of them. [SAVE] and [CONTINUE]. They pressed the [SAVE] box and another box said [Learning about the game of Duel Monsters fills you with DETERMINATION. File Saved.] Then the bigger box disappeared and the small two boxes of [SAVE] and [CONTINUE] appeared again. Frisk pressed on the [CONTINUE] box and all the boxes disappeared. Frisk shrugged, before heading back to where they were sitting.

Another 20 minutes passed and they sighed. They really couldn't wait here. They stood up and headed onto the next room. And the next. And the next. And the next. They explored each room and found some cards scattered in the occasional corner. There were five cards that they found and they seemed to share similar names. Frisk put the cards in their pocket and ventured forth. They eventually came to a place that seemed like it had a house there. They saw another glowing star, that they had dubbed as a 'Save Point' and headed towards it, when they saw Toriel coming out of the house. They froze in place and Toriel saw them.

"My child!" She rushed over to them.

"Are you all right? I am sorry for leaving you, it was foolish of me to expect you to stay cooped up in that room." Toriel engulfed them in a hug, and lead them into the ruins. Toriel showed them a room and declared that it was going to be their room for the time being. She pulled them away and into another room a where she brought out her own deck of cards.

"This my child, is a deck of cards for the game of Duel Monsters"

~~~~~~~~~~~~~~~~~~~~~~~DuellistTale~~~~~~~~~~~~~~~~~~~~~~~

Toriel smiled and sat them both down in comfortable chairs by the fire. She then started to explain the rules of the game and how to play each card. She explained what ATK, DEF, LP, Trap, Spell and Monster cards each were. Frisk followed her along intently and thought that they had a good grasp for the rules when Toriel said something, two things actually, that blew their mind.

"My child, Human souls are immensely more powerful than monster souls. Human souls can actually bend the rules a small bit. This is why many monsters want to absorb human souls. I shall explain what sort of things human souls can do. With one human soul, the user can 'Undo' up to 3 moves that they have done. Regardless if they have lost the duel or not. For example, if they attack and then realise that the opponent has the higher ATK or DEF card, or has a Spell or Trap card in the waiting, they can undo their attack, thus avoiding consequences. Having 2 Human Souls allows the user to use 'Undo' But also, disregard the need of tributing for level 5s and 6s. They tribute 1 less monster for each card. Having 3 is the same as having 2 but they tribute 2 less monsters. And with 4, its 3 less monsters. With 5 Human souls, its the same as having 4, however, they can also attack their opponent directly. 6 Human souls allows the user to special summon monsters from anywhere and everything else. However, with 7 human souls, they can completely disregard the rules and not obey any of them. This means they can summon their most powerful cards and attack as many times as they want, directly to your LP. This is why many monsters want to absorb Human Souls." Frisk was mindblown. So that's why Flowey wanted to kill them. To get their soul.

Frisk thanked Toriel for all this information and Toriel smiled mischievously.

"That's okay human, you are welcome that tu-Toriel!" Toriel giggled and Frisk face palmed and groaned into their hand.

After the terrible Pun, Toriel led them to a special back room. It had piles of cards in it.

"These cards are ones I've collected, feel free to make a deck out of them for yourself. Use as many as you want, but don't exceed the card limit!" She smiled and let Frisk run into the room with a look of wonderment.

Well, there you have it folks! The first chapter of DuellistTale! Now I need YOU the readers, to suggest what type of deck you thing Frisk should have. If you don't then I will. Also, I have a challenge. Guess what cards Frisk has already picked up and the first person to get it right will get something of their choice about the story! Be it an OC or bits of the Plot! Keep it mind I plan to do a Paci-Frisk so, no Sans fight. But that can be arranged if the first person gets it right and requests it. You have until I upload Chapter 3! So Good Luck!
