Faction change possible to be non KOS?

[CronosZ]

Given enough killing of Crushbone orcs, and the Faction standing improvments from that. Would a Dark Elf Necro be able to enter Felwith, or Akonan ?

I think its possible, but wanted to confier to see if im mistaken, or if the meer fact that im a Dark elf just means no.

Thanks everyone for your input.
