Oh, ok, I didn't realize the whole thing was still in planning stage. Alright.Well, if you have an idea, I would be interested to see it!
I have ideas on the crimson one, but didn't tried to make one yet. But it would be quite small-scale, like two small rooms, like 6 x 35 altogether or so (the interior I mean).
Edit: Does this thing generate underground or on the surface? Any real environment criteria, or something?
Edit 2 I hope you read this: Does it have to be made strictly of Corruption-acquired materials? That would limit my palette. I'm thinking about when Jungle Sanctums still existed on mobile and they had pearlwood lamps in them... Would some natural-gen inconsistencies like that happen here, or would we keep it to corruption stuff only?
