Leon had prepared all sorts of alchemy materials early on and was already waiting for everyone in the alchemy room.
Tassera arrived first; though she couldn't really provide much help with the alchemy... if anything, being a record keeper to jot down data was fine. She was simply curious about Leon's alchemy process and came by specifically to watch.
Cecilia, with her Jade Dragon lineage, was indeed quite a curious baby.
When Evil Dragons gather, it's bound to involve some kind of scheming. Fiora, being a Metal Dragon, quietly stood in a corner of the alchemy room.
Her head ached somewhat. If these Evil Dragons were plotting mischief, should she intervene? Leon wasn't actually that bad, and Tassera wasn't hard to get along with either. Maybe she could persuade them, maybe prevent any wrongdoing, but outright informing on them wouldn't be a noble move.
