You choice is your own elf. Asit tal-eb. If you are content living a life of scurrying about to no end than I will not stand in your way. The Qun is always looking for spies as well though. None will be turned away. If Par Vollen or Seheron was your home you would never lose it...only gain land and kingdoms when the time comes.
Panahedan elf
Eh... this might work on a city elf, but the Inquisitor doesn't really need a new purpose. They'll own an entire castle apparently... complete with servants. That's more than any Dalish could ever have dreamed of. o.O
edit: Actually, on a more serious note, no Dalish would agree to join the Qun because it's contradictory to the entire reason why the wander. The Dalish refused to give up their culture centuries ago, so joining the Qun now and giving up their culture wouldn't make much sense. Having a homeland isn't worth that... not to a true Dalish, I mean. There may be some individuals here and there who would take the deal, but it's simply not compatible with the Dalish mindset. You are better off checking the alienages for converts.
