Scriptum Ascenda
From Warhammer 40k - Lexicanum
The Scriptum Ascenda is an archive of the Imperial Fists aboard the Phalanx. Containing commentaries by Rogal Dorn on the Great Crusade and Horus Heresy, the texts are said to be shockingly blunt and manner of fact. Only members of the Imperial Fists 5th Company, Librarius, and Reclusiam are permitted access. Over time, however, the archive has become damaged and decayed and today what were originally great military schema and predictions of the future have been reduced to garbled prophecy.[1]
During the 13th Black Crusade over Cadia, the Scriptum Ascenda was badly damaged.[1]
