Just the place for the final showdown with whatever bunch of fanatics worship here...
Much of the ancient temple appears to have fallen into disrepair, and there's some nasty unidentified oozey gunk all over the place, but the lights and cages suggest some deluded fools still come here to venerate whatever this altar is dedicated to... and who knows, they may even summon it up!
With an overview sketch that shows how the relief works, a series of pages to paste together or a zip file with a really big single-page version (word to the wise, the same name of 'nogrid-complete' is used for EVERY zip file this publisher releases, remember to change the name if you buy more than one or they'll overwrite previous ones when downloaded!) for those using a virtual table top or who have access to a poster-scale printer, you have all that you need to set the scene for a climactic battle! And it looks good too. In a creepy sort of way. Just the thing for the intended purpose.
