(Motivation) Feared Assassin Sira

Lore
Might as well go out in a blaze of glory. Bereft of the will to live, Sira accepted a request long thought impossible to accomplish with one's life intact: the assassination of the king. Once she had killed him, his guards immediately lunged for her as expected, but just then, a hidden power sleeping within her demon's blood awakened. The pincers of a scorpion emerged from her back to match her barbed tail. Excited by the new weapons, she swiftly used them to cut clear through the soldiers' armor and eviscerate their innards. "How can I die after getting these new toys?"
