So I recently played Scape and Run: Parasites, so it's no wonder that I had this idea.
What if, in the eldritch spire, there were piles of taint with some tentacles, and they were covered in remains of thaumaturges. It could have a dark, decayed lump with goggles of revealing, and one tentacle shooting upwards with a caster's gauntlet at the end of it. I don't think it would actually be able to use the gauntlet, but it would still be interesting. It would give the feeling that the player isn't the first one who's been there and that the others weren't very fortunate.
