<Snipped quote by Aristo>
Given the Firebrands reside in the Claws and Zar Endal's proximity to the mountains I imagine we've clashed in the past or at the least have crossed paths before? On that note if you're looking for ideas, I don't know if the Phantom General would seek to take advantage of this but Zar Endal is currently vulnerable with Lord Alkhazar leading a sizable portion of it's military force to support Zar Vorgul. Alternatively if you're seeking to get involved in the main action at Vorgul maybe the Firebrands accompanied Alkhazar to the city? Just some ideas. :)
You're right - I think conflict between the Firebrands and Zar Endal would be inevitable, given their proximity. With Alkhazar away, it'd be the best time to strike; maybe Barsabbas had been waiting for this chance for a while.
Because Zar Endal is a Drathan state, it'd most likely perceive Barsabbas as an enemy, even with him no longer truly representing the Salished. That is, unless Alkhazar can overlook Barsabbas' origin and is willing to deal with him outside of the greater Drathan eye...
