As Era's daemon is one of her arcane summons - Carbuncle - I was wondering what would happen if she tried to summon one of her other Carbuncle variants? There are currently 3: emerald, topaz, and ruby.

I was thinking that maybe it could just change Emeraldd's colour, like when in-game you summon a different 'buncle when one is already out, though instead of disappearing it just somersaults into the new colour.

Or whatever you wanted to go with! I'm not sure how to go about it, but it is something my character would try sooner or later.
