The Mushroom Cathedral

Prompt #1 - The Mushroom Cathedral
Just outside the Olearius Spaceport stands a cathedral carved out of a tree that fell centuries ago. Instead of stained glass, carefully cultivated fungi decorate the walls and ceiling with exquisite depictions of the universe. The cathedral stands for no particular religion, but it is a popular place for marriages to be held. Draw or write your character visiting the Cathedral. Your piece must include your character in the inside or outside of a cathedral carved out of a fallen tree.
