Dimension Travel, a concept that sparked the imagination for many centuries and longer. However, to a certain Kalashtar being hurled through time and space against his will was something he did not appreciate nor expect. Even as colours he had never thought possible danced across his eyes, making him dizzy, he did his best to hold himself together.

Then out of nowhere, he was jettisoned through a portal of some kind, rolling uncontrollably on a cold hard stone, until he impacted the wall with a thud. The man groaned as he held his armoured hand to his head, before shaking his head and standing up on his own strength. The man was known as Kanatash, a Kalashtar.

The Kalashtar were a fusion of men and spirits called Quori, which gave them certain unique abilities and bound their souls to their particular Quori. The man in question was wearing a half-plate armour, alongside with a shield, which completely covered his body, making it almost impossible to tell the gender, age or anything like it.

The armour and the shield were unique, made through the hard labour of his team and composed entirely out of non-metal materials, due to him being a druid. The half-plate was made from the chitin of the purple worm, further reinforced with magic, making it almost as good as full plate armour. The second one was a magical shield, made from hardwood, which was far stronger than an ordinary shield. Both of the items were magical in nature and could repair themselves with a bit of magic.

The man looked to his right and let out a relieved sigh as he noticed the weapon in his right hand. It was a legendary Defender, a longsword which could boost one armour class and prevent damage from hostile activities. There were, of course, many other items he acquired over his adventures, like the Bag of Holding, which allowed him to store a great number of items without a problem.

However, that wasn't important for now, as he looked around the area. The first thing he noticed that he seemed to have found himself in some kind of cave, judging by the lack of light and stone surrounding him. Luckily for him, he had Goggles of Night, which allowed him to see in the darkness, even if only in the shades of grey.

As he pondered what to do next, he noticed that he was alone in the cave. Not a single member of his team was here, which honestly relieved him. Last time he saw them was when they were fighting the damn Lich, who proved to be quite a challenge. They have managed to kill it, but not without complications. As they tried to escape, he failed to hold on to the floor and was sucked in by the portal, sending him here.

He had no clue what happened to his companions, but he saw them alive and well, so he hoped they were fine after all. With his mind calmer than moments ago, he set off to explore the cave and possibly find an exit. However, he had no clue what kind of monsters dwelled in this cave, so as a precaution he cast a spell known as 'Pass without Trace', before making his way through the Dungeon, sneaking all the way in, he footsteps silenced, just like he did many times before.

Far away, a pair of gods were watching with surprise as a new piece entered the play. The two were known as Truth an Illusion, with the latter looking like a young girl.

"That's unexpected," She said as she looked all over the adventures. "Hey, Truth, what do you think, is he strong?"

"Let's see...," Truth replied as he tried to discern everything about the individual.

At that moment, a d20 die was rolled without a prompt, before it came out at seventeen. Truth frowned as he took a die of his own and rolled fifteen, which prevented him from scrying on the individual.

"What the... That's not supposed to happen," He said as he glared at the piece.

"Hahaha, he rolled better than you, didn't he?" Illusion said as she smiled innocently.

"You know that shouldn't be possible, don't you?" Truth countered as he began thinking of a way to circumvent it.

"I know, but it's way more fun this way, don't you think?" She replied and watched with amusement as the man-made his way through the Dungeon she made herself.

"Fine, whatever, he will most likely die anyway and if not, it might make a game more interesting," He said.

Internally he was quite curious himself. A new piece, something he hadn't seen before was on the board. As long as he didn't turn into another Goblin Slayer, he would take it. The last thing he needed was the two meeting and devoting their entire life to clearing out trash mobs the goblins were. Oh well, a demon, a dragon would suffice in that case.

So, here's an idea that has been on my head for quite a while. Since Goblin Slayer is a D&D basically, I figured, what would happen when one of the adventurers came and messed things up.

I don't think I will write a full-fledged crossover, simply because I don't know the setting that well, or even D&D that well.

The main problem I have got is that I am not sure how to handle Goblin Slayer and his companions. Like, I like the guy, he is great, a medieval Doom Slayer.

However, I don't want to either a) Kill him, b)Save his village so he doesn't become a Goblin Slayer, c)Get him over shadowed by my OC d)Steal his entire harem.

So, that's where you readers come in. Tell me, how do you imagine a crossover like this would work?

As for now, Ediros signing out.
