World's Largest Dungeon
Achsyyx is an imp who used his powers to commune with infernal powers to learn about a long forgotten chapel close to the entryway of the dungeon that held a gateway to an extradimensional space where multitudes of infernal beasts lay. Achsyyx convinced Longtail to become his master and use his charm to lead a group of humanoids into the dungeon to find the chapel. Longtail lied to the humanoids and told them they would find treasure in the dungeon. Led by Lizardfolk guides the group entered the dungeon and Longtail found the chapel. He found he was not able to controll all of the infernal creatures, to the delight of Achsyyx.
