It was glimpsed at in S1. Act V that when stimulated just right (no pun intended) by Daniel's Synergy, his girls can do more than just scream in constant pleasure while squirming on the floor. Alyssa conjured a fireball in her hand, Specca manifested water, Luna and Falla generated gusts of wind, and Squeak became much stronger physically.
So here's something to consider. If this ability was mastered by Daniel and his mates, and the girls could also gain new tricks and abilities, either from themselves or possibly each other, what kind of fighters for peace and equality in Eden would they become? The limits to such magic and mystery are rather immeasurable some may say.
