The cohort would be the reason for me to do it. I'm not interested in the followers. We don't want to be too big of a band.
Do you want to stat out the cohort (Probably 4th level, as I prefer not to spend a manifester level on going Thrallherd, though maybe it befits the setting more), or want me to? In the latter case, what are the rules on stats and gear?
Zaer> In regular D&D divine casters can get the energy for their spells from all kinds of sources, so they don't have to worship a priest. In Dark Sun, the Elements and Subelements are the only ways for Cleric to receive their divine powers (Druids get theirs from the fauna and Templars get it from Sorceror-Kings), but since in your case it's psionic and not divine magic it might work.
