The 100 Level Dungeon Tower.

The Tower is no ordinary tower at all, it’s a dungeon with 100 floors that we know of, filled with creatures and monsters. The tower is divided into sections, with the lower levels being 1-25 filled with what we call common creatures like Goblins: the more weak and common than the rest, Kobolds: dog like creatures that appear in packs, Lizardmen: more challenging reptilian creatures, Minotaurs: strong, bull-like monsters, Gargoyles, Orcs: Larger, boar-like brutes, Killer Ants: Swarm-based insects, and Armor Parasites. Then there’s the Upper middle levels being 25-75 that hold the same creatures from the lower levels but also more rare creatures like the Mermaids: often encountered in water areas, Black Rhinos: Armored beasts requiring high-level adventurers, Hellhounds: Fire-breathing dogs, Undead : Various ghost or skeletal types, especially in deeper areas, and the Juggernaut: An immune-based anti-adventurer creature that "cleans" the dungeon, capable of tearing through walls. On the last 25 levels we don’t even have a name for because no one has reached those levels, but it’s been rumored that one man has reached the highest floors but he was never heard of again, they say that the last 25 level hold more dangerous creatures like Xenos: Intelligent monsters that are considered aberrations by gods and humans alike, as they possess individual thought, language, and culture, Dungeon Avatar: A humanoid entity created by the dungeon itself to combat adventurers, including all the other creatures from the other levels, all creatures drop crystals, some small, some larger depending on the creatures slain, the the crystals is the very essence of their life residing inside the body. They can be exchanged for gold at the Crystals Exchange centers around the city. Than outside the tower is a large beautiful bustling city known as Vanyth, full of merchants, smiths, inns, guilds, and all the things known to be in a bustling city with the Tower being in the center of it all.
