Sacrificial Temple

Fairly simple from the inside, unfortunately, which in my experience is the opposite of most architecture. Still, the large squares ARE ten feet, so sized appropriately there's still a lot of majesty to be had.

This temple is directly inspired from a recent game I've been playing, although its inspiration is a small part of a much larger game. Brownie points to anyone who can name the game (and the monster in question, I can't find the game guide for the life of me)!
