Nicely done
I've just done the "Gnosling" (I renamed the Gremlin) and have started work on the "Thade" (same deal with the Anomaly). Will get a screen shot added shortly.
Have you managed to get the Ottomans extracted? Archers, Swordsmen and something "Champion-ish" would be useful if you can find them in there. The Cavalry-line is probably going to be mostly denied to them, so no worries there.
EDIT: Screenshot of the Gnoslings. Thanks to Winddelay for helping to solve an issue with the reflection map for the glow on the staff (which was inherited from the goblin's spear).
They're currently implemented as "Gate-Creatures", 2
2
, 1 MetaMagic affinity, casts Metamagic 1 + 2 only, PostCombatGainKnowledge (gains extra experience when it defeats an enemy of equal or higher level).
EDIT2: I'm looking at another concept for the Psion as well - quite drastically different from the "mage look". Basically appearing as massive beings created entirely by the will of an extra-planar being (namely one of Mammon's demons in Oghma's vault). Significantly higher base strength than an archmage, but locked at Mind3 (no other spheres) and only Mind Affinity. Appearance-wise - probably based on the Nullstone Golem...
The Mage's really suit the Oghma side of the Kahdi, but the Psion is only obtained after siding completely with Mammon - it's a being of power and ambition and the visible projection of that reflects it.
