What book's Temporal Reiteration from?
Oh, and if it wouldn't mess up the legion too much, make the beginning character an Elan.
They get a set of four feats that grant you bonuses on their racial abilities.
The new abilities they get are:
-Never need to Eat/Drink again
-When you get attacked, you can lower the damage by 4/pp. You have infinite PP
-Get a +6 racial bonus to saving throws by spending 1 pp. Lasts a round. TI means that it's permanent
-Retain your psionic focus by spending 3 pp.
Sadly, it's a race with -2 on it's charisma, but you are freakin' tough to kill.
No one can damage you, you have a +6 on saves, you don't need to eat or drink, and whenever you expend your psionic focus, you get it back immediately.
I love Elans. Now if they only went well with bards...
