Psionics are fantastic for odd ball builds, Ardent especially thanks to its ability to multiclass rather well (if you take it as it is out of the book, rather than what the author intended).
Thing is, Psion just makes you a wizard-but-not-a-wizard. Refluffed, slightly different system, but you're in essence, a full caster with a slightly different list. You don't really bring anything that mechanically unique that a wizard can't bring. Psion, in my eyes, is an alternative wizard spell-list, basically, wizard-lite. Or, if I want to break the game, have Spell-to-Power Erudites be a known thing in the setting and have it Psi-Chirurg itself into my brain.
Ardents, you have none of that. I like to treat them like a 10-level fast advancement prestige class, with Dominant Mantle as the capstone, requiring Practised Manifester, and 4 previous class levels. It's a slightly strange way of looking at it, I know.
As for race, Hadozee are pretty damn cool, and you never see them. One - Flying squirrel gorilla things are pretty fucking cool. Two - one smoking a blunt is pretty hilarious to imagine. I imagine him to be something akin to a more modern version of King Louis from the jungle book, perhaps a distant relation.
Ardent 1/Swashbuckler 2
To advance, make sure you let them know about the Swashbucker dead levels. You'll look like Ardent 1/Swashbuckler 4, then at 6th level, you can take Ardent 2 and Practised Manifester for ML6 (5pp powers), and at 7th, you can, if you wish, get your grubby mits on Metamorphosis, or Psychic Reformation. I love me some Psy-Ref. PsyRef is ace. Sure, it costs XP, but you get to change your entire build (Feats, Skills, and potentially powers etc) with 10 minutes notice - or even quicker, with access to Linked Power at 9th, say - which would need Psionic Meditation to make it worthwhile.
Linked power allows all sorts of action economy breakages to occur, but with Linked Power, it means you can literally go in the middle of a diplomatic mission from "I AM REALLY ANGRY YOU DON'T WANT TO MAKE ME ANGRY" to "there there, dear, everything will be alright".
Anyway, I can't be arsed filling in a fancy sheet;
