Cant wish for Grigori, aka lord of civilization?

[Kuritza]

Actually, it's more of RP issue. Freeing a Grigori is much cooler than just wishing for Seraph, even if Seraph is a stronger SC chassis.
Also, some diversity wouldnt hurt. Having more options is fun.

Except that you can only "free" a Grigori through massive blood offering. And the only ones with such knowledge, are the giants of the Valley of Hinnom.

Your astral pearls are useless here!
