Padus is the chaplain of the 13th company. He's a native Sicarian, though he lacks any appreciable amount of Colchisian blood. He is also relatively young, a mere two millennia. He has, however, been quite active during those years, fighting in a number of Word Bearer and non-WB warbands, both inside and outside of the Eye. He is called "the Dreamspeaker", because he never communicates verbally (it isn't know if he can't speak or simply won't speak). It is extremely rare for a Word Bearer, and especially a chaplain, not to speak - all the time. Instead he addresses his company through dreams and visions - or brute telepathy (which would seem to indicate that he's a psyker or sorcerer of some sort).
