Plane of Chaos
Slab

This is a board that I made for the end game to my campaign. It is the Plane of Chaos and home to the Fang Lord, a giant bone dragon that summons skeletons and raises dead.
The wall in front on the travel orb is a rune door that players need to collect the runes to open the door. After the runes are placed on the slots a riddle emerges on the door. Earth (rune 1), Sun (rune 2), Moon (rune 3), Star (rune 4) and the answer is The Universe. They then answer the riddle and the door opens.
It’s a shame it’s too dark to see any detail in the screenshots. :/
