The two villainous members of the notorious Four Horsemen were both seen entering the inner sanctum of Lord Recluse himself. Once inside the two each pledged themselves to one of Recluse's top lieutenants.
Mz. Ivy aligned herself with Scirocco. Formally known as Imad Malak, Scirocco was not always a villain. Once he was a freedom fighter, battling against tyranny in the Middle East. While in the Baka Valley fleeing mercenary death squads he discovered an ancient tomb and stumbled inside. The tomb was that of a long-dead desert hero, and within Malak found the heroes scimitar, an ancient weapon that granted the wielder incredible powers. Malak took the sword and donned the mantle of Scirocco, the Desert Wind. He intended to use his power to free his people but in taking the items he fell under a curse. Everything he did was tainted, bringing greater evil to the world. Once a hero of the people he had become a dark stain on their proud heritage and was cast out. Scirocco continued fighting, earning a grim reputation both for his phenomenal powers and for retaining some of Imad's old principals. He soon came to the attention of Arachnos and accepted the invitation to join Lord Recluse's inner circle.
Meanwhile, Death-Adder has aligned with Ghost Widow who appears to be an actual spirit from beyond the grave rather than a super being with some sort of incorporeal power. Some have said she was once a rising star in the Night Widows when she was slain. Her thirst for vengeance must have been great, for she returned from the void and now serves at Recluse's side. There are rumors that her service isn't entirely voluntary however.
