Both came through fine. Purity of Soul + Child of Khyber is an interesting mix as those two can be seen as a bit opposed. The pyro is fine, but I'm going to propose a modification that is all arcane based instead of psi-based and its tailored exactly to aberrant dragonmarkers:
Flame of Khyber
Prereqs. Concentration 8 ranks, Craft (alchemy) 1 rank, Knowledge (arcana) 2 ranks; Aberrant Dragonmark (burning hands, produce flame), Must of set a fire just to watch it burn.
The Flame of Khyber class skills (and the key ability for each skill) are Climb (Str), Concentration (Con), Craft (any) (Int), Intimidate (Cha), Jump (Str), and Spellcraft (Int).
All the abilities would be the same save for Firewalk and Heat Death except their Spell-like where appropriate. You're not going to get enough levels to get to Firewalk IC so I'm not going to worry about a rework of it for now.
Essentially, this translates as one free feat (since Wild Talent isn't needed) and a few skills to move around.
As for history, the only caveat I have is that remember House Jorasco is the company to go to for hired-healing; the Church is not in the healing business. However, I can see Tessa perhaps volunteering for the war effort (possibly against her superior's wishes) in order to heal as sort of a counterpoint to Jorasco's more capitalistic services.
