Echoes, Fragments, Parasites, and Symbiotes

[Mystendanian]

I just picked up the Quintessential Psion from Mongoose and was wondering if anyone is running a campaign that has implemented any of these elements. If so, is it balancing out pretty well or is it dramatically unbalancing the psion?

Although they all seem pretty complex, I think they'll definitely add some mysterious flavor to the game. IMHO, well done Mongoose.

I haven't seen it, myself. Do they primarily add flavor or power?
