You and Anton push open the door, finding yourselves at top of long dark staircase od old Rusted stone. Moving down, the steps were covered in old bones and shattered skulls that aged a pale brown with decay.

The Crypt. A dark place where the dead seem find themselves within the Dungeon of Change. Made of tall but rather thin tunnels lined with bones and debris of the once living.

For those new, here is the start of the Dungeon of Change series: Darkwood

Generally recommended to start there to understand the lore a bit more and the character Anton Goebel.
