No living creature knows the true origin of Signus. Some claim she* is a wraith, bound by vengeance and controllable only through dark magic. Others insist she is simply a mage of the highest caliber. Others still believe it to hail from another planet, or possibly another dimension entirely. But all can agree on its unparalleled killing prowess - capable of exterminating virtually anyone, anywhere, regardless of the conditions or defenses surrounding its target. Even those who contract Signus can rarely say for certain who their assassin is. It has been seen consuming the bodies of others and adopting their appearance afterwards; descriptions of its "true form" vary wildly. The most consistent pattern in those believed to have been Signus is the manifestation of ethereal lights when forced into open combat, commanded through unknown means to blind its opponent or burn them to ashes. Signus' one and only failure to kill a target was against the Jungle Tyrant, Yharim. Manifesting from nothing in the inner sanctums of the Jungle Temple, it was foiled only by its target summoning of the Devourer of Gods to his aid - and even then, Signus evaded death for an extended period of time within the Devourer's own dimension. Both of them soon came to realize that neither could kill the other; a grudging ceasefire was eventually agreed upon, which slowly evolved into an agreement of mutual respect. Signus itself became the Devourer's favorite means of eliminating targets when delicacy and stealth were needed over sheer power and size. Of the three Sentinels, none is closer to fulfilling their current objective than the ethereal assassin.
