[sector24]

Greek mythological creatures are pretty well covered in dominions. The problem is that most of the creatures not used are thematically at the pretender level rather than the summon level. Cyclopes and titans are at the pretender level, so a summon like the Hecatonchires wouldn't really make sense (unless it was banished to tartarus, in which case it is already in the game).

Not saying it couldn't happen, but it might be problematic. The only thing I can think of that isn't covered is something like stymphalian birds. In game terms they'd be flying mechanical men I guess. Also, you could further split nymphs into their classifications:

Melissae
Nephelae
Oceanids
Nereids
etc.

Hard to say exactly how they'd be different from each other though.
