This post inspired me most comments; although I never cared much for Laanx so far, to have an unforgiving, harsh religious faction is very enjoyable in a fantasy world.
My first comment applies to other submissions as well: don't give a large sum of money as the 1st reward (10 FP). Riches are for important and trusted members only; 5000 tria to every new face is neither sensible nor sustainable.
In fact, at this level, I would give either tria or FP. The choice is to take a reasonable payment for the given task, or to forfeit it as an offering to the cult, thus opening yourself a path for future favours.
In a general way, I believe rewards should be, as often as possible, openings towards new things, rather than magic trinkets and buffs. That without further closing the paths for other personal development (like reduced physical abilities, which makes no sense).
Back to the Iron Hand, and reading that the faction contains priests, warriors, and even assassins. You don't want everybody to try to become a priest, I suppose. So, the reward at 50 points is also a choice: choose the path of the priest or the path of the warrior (like crusaders or inquisitors or whatnot).
50 points reward:
Position as a student of sacred texts or Position as a warrior/monk trainee
Religious robe(s) or Religious surcoat
Access to libraries or Access to barracks
Acces to good CHA-skills teacher or Access to good combat teacher
70 FP reward:
Access to barracks or Access to libraries
90 FP reward:
Priesthood robe or Inquisitor armor
etc.
As a basis, I'd see the warrior path more physically rewarding, and the priest path more politically (and maybe financially) rewarding. Not so much about magic, which can be achieved through personal training anyway, or even through another faction.
PS: For religious factions' quests, I'd very well consider 1 or 2 pilgrimage quests, one at low level, one at higher level for example. Better leave that aside until the game map is larger, though.
