Into the Dungeon 4/3/2023

The adventuring party has been hired by the King to make their way through a canyon that was made into a Dungeon. The dungeon was made by dwarven hands. It was made for the worship of an evil deity. Evil still resided there to this day. A wizard has taken the dungeon for himself, creating it into his own image of evil. It is being used as a stronghold, security for the days to come. The wizard hears omens of a necromancer that threatens his plans. He has recently cleared out most of the inhabitants in the dungeon to relocate. There are some left over people taking care of the rest that needs to be relocated. The wizard lilith took the sight. She discovered it in shambles and with many dwarves dead inside. They stumbled upon a huge nest of Kruthik.
