Tluam, Sister of Vrag

Tlaum, Sister of Vrag is a Cabal Colossus seen in the European Aerial Zone along with her sister Vrag, serving as a commander for the Red Legion. Assuming by her appearance with her sister, the two serve as Bond Sisters of sorts, together obtaining control over a large Cabal battalion and attempting to seek control over the EAZ as a new base of operations.

Gameplay
Tlaum, along with Vrag, will spawn from their respective Harvester along with a squad of their own Red Legion troops. There, Tluam will hold the Courtyard with her sister until her sister is killed. Once so happens, she will receive a health boost and retreat to the Ruins/Garage and summon a Thresher to hold the Courtyard while she's on the move. Once killed, either she will provide a boost to her sister or both their deaths will spawn a chest for the Treasure Hunt encounter.
