Slaughter, sacrifice and barrels of blood - what happens here is unequivocally evil.

Comments:

Entrance is solely through the right portal that will teleport you into the portal on the left.

Chamber, centre left is for blood draining.

The central, demon-shaped chamber is for communion rituals with demons, demons may appear in the pile of demon skulls there ('the teeth')

Hope you can use this map, it was fun to make.

Build time 6 hours (but that was honestly because I struggled to get the 'face' right with the resources available).
