Lady Keletress is a commander of the Burning Legion. Keletress was present at the Battle for the Broken Shore. She is cruel and enjoys sowing chaos. Thus, she has made it her personal mission to wipe out the monks of Azeroth, seeing their quest for balance and order as an affront to the Legion.[1] She also has large green wings, which is unusual for an eredar.
The fact Keletress has wings may imply that she is a Doommaiden considering the model of these winged eredars were added in the game only in patch 7.3.0.
