She appeared unexpectedly in 980.M41 at a crucial moment of the Promethean War on Heletine, where the
Order of the Ebon Chalice and the
Salamanders Space Marines were engaged with forces of the
Black Legion. There she turned the tide against the
Chaos Space Marines and drove a spearhead directly to the Daemon Prince Lord Gralastyx, and ultimately slew him. When the dust of the victory had settled, however, there was no sign of her. It remains unclear if this happened during her life or after she had been declared dead on Forrax.
