#To dip into a different fandom: this is nearing Kirkwall-tier shit. With less demonic activity but still a worrying amount of evil god.

For lack of any insight into what the hell the underground chapel was built for, aside from worship of something very old, I'm just going to assume one of Mephistopheles' cults built it for fiend worship or something and then later a rich merchants-turned-vampires family built a house on top. The sigil is a bat with horns, if you squint it can be a stylised symbol of the bat wings and horns Mephistopheles has...

Of course it could be connected to the network of crypts and undead recently discovered in the cliffs. I don't know, like there's an entire ancient city built underneath the modern city with no canon lore explanation either. Could all be a Netherese construction?

Baldur's Gate is just a fucking weird site when you scratch the surface.

It was built because the cliffs form a perfect natural harbour, but perhaps that's just the lure into a trap...
