Lady Sacrolash is an Eredar demoness, from the shattered world of Argus. She is one of the Eredar Twins, together with her sister Grand Warlock Alythess. They currently stand together to defend the Sunwell Plateau against the Shattered Sun offensive. As a demoness, Sacrolash is very powerful in magic and combat, as well as seduction and allure to subvert enemies. While her sister prefers fire, she prefers shadows. She is the gentlest and most subversive of the twins, opting for subtle spells.
