I'm currently playing-
Synad half fey
Psion 6/ thrall herder 5/factotum 1/ dragon shaman 1/ cleric 1/ marshal 5

I took cleric for a couple of domains that either boost my aura effects or create effects like aura's.

factotum was for able learner so cross class skills disappear

I took all classes for fluff reasons and they have all proven to be useful :)
The idea is we are in a kingdom building campaign where we all rule a small kingdom and are coming together to build a bigger one.

so i'm a psion, full progression. and everything else i am is to gain the trust of people. have people follow me. and then boost said people to make them superior to others.

its not optimal but its really fun.
