So what would a Mage of Doom be able to do? What kind of challenges might they face and maybe a bit about their personality//habits if it's not too much to ask... Thanks! <3

Congrats on being Sollux! He seems to struggle with Doom quite a bit- He knows about the voices of the imminently deceased, and about their own fate to be doomed, and he can do little about it which make him get quite grumpy. Still he tries hard, to save Feferi pre-entry, to get shit done in the Session. Manipulating the Meteors of the Reckoning with Aradia to blast the Black King could also be seen as quite the Mage of Doom-y thing. A guide to avoid the Doom you’re facing, but also struggling because they’re constantly thinking about it.
