Martio Imprimis
The Martio Imprimis is a song chanted by the Word Bearers, that was crafted by the Primarch Lorgar; in the days before the Emperor turned upon Lorgar and his Legion. Though it is still chanted by the Word Bearers millenia later, the meanings of its strange words are mostly lost to them.[1]
