Taken from her village at a young age at a young age and trained as an Invoker, Illyana is the former leader of Stormcrow's Hunters. She turned against Blackblade after learning that he ordered the eradication of her clan the Swordweavers. Stricken by grief, she walked into the Unending Fields and found herself back in the village, mere moments after she was taken. The elders bestowed her with the Cloak of a Hundred Billion Stars, so that when the time was right Blackblade would see her coming, and the power of their clan's Timelost Conjuring.
Upon death, the bones of members of the clan turn into magically infused metal, which is then shaped into a weapon. Timelost Conjuring allows a Swordweaver to pull these weapons from a plane at the end of time instantaneously, and use them at their discretion.
In addition to the cloak, she wears the traditional grey and blue garb of her clan underneath a light suit of armor. She travels on Champion, a spotted deer from the forests of Elkwood.
