Quick crunch question, CR 1/2 seems low for a Suli with a class level in Ranger. Is that right in PFRPG or just a typo? with its powers CR 1 would seem more appropriate (still thinking 3.5 though).
Here's my thinking on this.
Compared to a human ranger 1 (CR 1/2), the suli ranger 1 has a net +2 to his ability scores, low-light vision (generally irrelevant to CR), +1d6 energy damage to one attack for one round, and resistance 5 to all energy.
Compared to a human ranger 2 (CR 1), the suli ranger is -1 BAB, -1 d10 Hit Die, -2 in overall saves, -1 combat style feat, and -6 skill points (generally irrelevant to CR).
Clearly the suli is somewhere between the human ranger 1 and the human ranger 2. The bonuses compared to the human ranger 1 don't do a whole lot to make him a more dangerous opponent, whereas the shortfalls compared to the human ranger 2 (in particular, having half as many hit points) make him significantly weaker. So I'd put him on the CR 1/2 side of the board. There are situations where the suli ranger 1 is going to be better than a human ranger 1 (say, an encounter where everyone is taking energy damage every round), but under those circumstances the GM should feel to award the PCs more XP (say, by treating his CR as 1 higher).
You can interpret it that way, yes, though Kelesh itself is really the heart of the empire and Qadira is but its western extreme colony.
Kind of like those little kingdoms real world empires used to keep on their borders as a way of slowing donw any thrusts at the empire proper? I.e., the later Byzantines and the Slavic kingdoms, Persia and the Lakhmid Arabs, etc.
