In any case, our rugged peplum hero comes along first and saves the day. But hey, check out that portal!
Like, did they build the temple around this portal they found in nature that somehow already existed? Has it been there forever and humans found it and decided to build a whole thing around it since it was unknown and unknowable? Or does something that the humans are doing in the cathedral trigger the portal’s opening? Could they have built it anywhere? Can they build more? What ancient arts allow them to do this? I guess all this is up to you, but here’s a bit of the piece in full resolution:

If you’re taken somewhere really great though, by all means, attribute that to me. You’re welcome. Here’s the whole thing:
