From the preview:
The witch Kethra A’laak stands apart from all others within the swarm. Although sworn to the Blood Coven which taught her, great and terrible ambitions burn within her, and her elevation into the coven has only strengthened her dreams of conquest and glory. Considered unpredictable by many of her peers, Kethra’s ruthlessness is not out of place amidst the sisterhood of the Blood Coven.
Now as the battle for Terrinoth pitches the realm into chaos, Kethra A’laak sees her opportunity to seize power and take her place as the ruler of the locust swarm. Fantasy Flight Games is pleased to announce the upcoming release of the Kethra A’laak Hero Expansion for the Uthuk Army of Runewars Miniatures Game!
