Haraguni Shiho, otherwise known as Strigidae One of the Court of Arcani, served in Kratesis' personal guard, and as such, held a special prominence within the Court, heralded as quite possibly the greatest of the Strigidae. Even through mixed personal feelings from various others within the Court, many thought it was time for her to move on from being a simple Strigidae, to take on the title of Strix. The only further necessity was a test.
Enter Tony Stark.
Some time ago, Amaranth and a band of allies assaulted Peak Tower in an attempt to assassinate the businessman/ armored "hero." After that attempt failed, Stark retaliated, sacking what was the base of Amaranth and his cadre of Renegades in the Sahara Desert. Seeing her cherished, the only person in memory to show her true affection, in such a battered state, she saw this test and promotion as an opportunity for recompense. To take down Stark, to receive a promotion, taking care of two issues simultaneously. And so, using members of a terrorist cell of Court affiliates, she springs a trap.
This is me, Strigidae One, versus Tony Stark. You all know who he is.
