The Hole

Well, here's the prologue:
Nine years ago, a machine Called the "Capital Walker" was built to find a safe place to put the capital city and the "Red House". When it found the place, it was about to put the capial and the "Red House" down, a mysterious silver-blue vortex appeared in front of it. The votex blew up the "Capital Walker" and it fell, coincedently forming a tunnel that conected its footprints. The footprints were made into cities, and they were inhabited by goblins, dwarves, and elves. LIfe down there in the "Domes" was the same as up on the surface, exept the elves gave the Domes their technology so the Domes have a much, much more advanced technological world. The tunnels have grdually become infested with monsters from the "Overworld". The "Overworlders" built special labyrinths to contain monsters in. they put many common, unnoticeable monsters in dungeons and one noticable, unique monster guarding the exit called the dungeon "Boss". These dungeons eventually became used as training facilities for adventurer's guids, bounty hunter guilds, and mercenary's guilds. Aparrentyly the vortex (known as "The Hole") corrupted the creatures and turned them inro these monsters. The Hole seemed to have corrupted some humans too, and turned them into smarter, stronger monsters known as "Bosses".
It has been almomst 100 years since "The Incident". The "Red House" was wrecked and the "Chanore" was killed. They were replaced with a King and Queen in a Castle. (I know kinda cliche, but it's kinda funny considering this takes place in an alternate dimension in a post apocalyptic time.). No-one knows what happened to the magical "Domes" and the "Dwarves" and "Trolls" and "Elves" and "Goblins". Monsters are still trapped in "Dungeons" (in case you play the game and the walls of the dungeons look man-made, that's becuse they are.).
