If this is the case then they forgot (hehe) Irrigo, also Monstrous Anatomy looks more like it than Peligin, it being so violet.

Personally, I think it'd be better for Glasswork to be Cosmogone, both for silverers and also to not have a redundant Viric; also for Shapeling Arts to be Irrigo (Do you recall how they came to that place? If only we could remember...)
