Euphrati Keeler
From Lexicanum
Euphrati Keeler was a remembrancer attached to the 63rd Expeditionary Force in the closing months of the Great Crusade. An imagist of some renown, her images included the rescue of Maloghurst from the surface of Sixty-Three-Nineteen, Garviel Loken taking an oath of moment, and images from the Whisperheads on the surface. She was shaken up by an encounter with the demon Samus in the Whisperheads, which may have contributed to her eventual joining of the Lectitio Divinitatus, a cult that worshipped the Emperor of Mankind as a deity.
Her devotion to the Emperor became clear when Kyril Sindermann accidentally summoned a demon using the Book of Lorgar in the library of Warmaster Horus' flagship, the Vengeful Spirit, as she stood before the beast and banished it back into the Warp. She went into a state of what could be described as catatonia. The word went out throughout the 63rd Expedition, leading the Divinitatus members to see her as "the Saint", the venerated prophet of the Emperor. She became the target of Horus' assassins, including Maloghurst's enforcer Maggard. She awakened shortly before the battle of Isstvan III, and warned that something was afoot. She witnessed the bombardment of Istvaan, and approached Iacton Qruze to escape the Vengeful Spirit. She escaped from Istvaan onboard the frigate Eisenstein, commanded by Captain Nathaniel Garro, a Death Guard loyalist.
The Silent Sisterhood believed that Keeler may in fact have been a renegade psyker. She was taken to their fortress monastery on Luna and questioned; her fate afterwards (as the Horus Heresy Series is incomplete) is unknown.
