Generic Lich Lair (The Monster Overhaul) Board
Use this board as a simple lair for your lich or dungeon delve or use this alongside the Monster Overhaul to generate enemies inside.
Comes complete with Hide Volumes, and is system agnostic.
The Monster Overhaul is a system agnostic book full of random tables and monsters written with incredible flair and full of resources you can use on the fly to make your world feel alive. I love this book and will be using it for many adventures in the future.
