Suli bat-Keren was a cheetah evolved by Israeli Jewish Fundamentalists to combat the power of the Sacristy. She was ultimately captured and reeducated by Archangel Zadkiel, and set free shortly before the archangel was purged for heresy. Realizing that all of Zadkiel's former triumphs would be called into question, Suli fled the church, seeking to recreate the experiment that a missionary and a skinlyn had used to evade capture by the Archangel Jehudiel and, later, even the searches of the Inquisition as a whole.
Coming upon the last known contact between Heretic's Missionary Transport and Jehudiel's Scion; the MTV Gallant had been locked in stasis around a singularity and, even now, Ecclesiast scientists were working frantically, trying to decode whatever event had happened here before the stasis failed and the Gallant was lost forever.
