Varesh Ossa

Warmarshal Varesh Ossa, a female Dervish, is the leader of the people of Kourna, and a direct descendant of Turai Ossa. She is held in high regard by most Elonians.

Varesh is shown on the Guild Wars Nightfall Collector's Edition box art, easily recognizable by her distinctive bronze/purple armor with a large metal banded collar. The Nightfall Collector's Edition also contains an access key to acquire a Warmarshal Varesh miniature.

Her miniature is supposed to be updated with a scythe and a greater length in a coming update (source).

Warmarshal Varesh, like her mentor General Kahyet, is a worshipper of the fallen god, Abaddon. She has a key role in attempting to bring about the Nightfall.

In addition to commanding the army of Kourna, Varesh has a host of Margonite soldiers. Some of Abaddon's stronger demons are in her service as well, including The Hunger, The Blasphemy, The Drought, and Harbingers of Nightfall.

By the time she reaches Vabbi, she has begun transforming into a Margonite, with purple eyes, graying skin, a receding hairline and forehead ridges. After she is killed in the Ruins of Morah mission, Abaddon revives her as a full Margonite.

What many people do not realise is that later on in the game, Varesh's appearance changes, with stubs appearing on her forehead that resemble the Margonites.
