Though her family believes her to be dead, Isyra was in reality stolen to be raised in The Dark Garden, one of the Spider Prince's secret academies. She professes to have no memories of her family, but in her heart is a shadowy figure that she believes to be Raja Rudatha himself. Isyra commands the Black Widows, a regiment that doesn't officially exist. 

She is a descendant of Ghora Zikia-Zara, The Poisonous, and Dusaka Urugal-Lul, The Fatale. 

Her sigil is a hanging spider displayed on a divided field of greens.
