Well, I like Ascelia, but she is burdensome so I would likely be better off without her. Maybe, if the chance comes up in the future, I can bring her back, or even another Master. For the time being, though she's fine to fade in the background.

That is an approach that I think that could work. Have the Master fade away when they are not important, rather than outright puffing out. After all, they can still be interesting in some interactions. Especially during downtimes. That's just an opinion, really. If it's too complicate to understand, just think of out like those RPG characters that aren't in your active party but will come out during cutscenes to say their piece and populate any hub your party has.

Anyway, Ascelia cleared to go, since she's being of little help/interest at the time.
