Gurda Wildmane is a level 35 quest giver and the leader of Ghost Walker Post in the contested territory of Desolace.
She starts the following quests:
[33] Magram Alliance (Friendly)
[33] Gelkis Alliance (Friendly)
Note that although it is possible to do both these quest by first choosing one faction to complete, then betraying it for the other, most people choose to pick one and stick with it, and ignore the other.
