From Warhammer 40k - Lexicanum
Martellos is an Epistolary in the Blood Angels Chapter.
Martellos is coldly calm in battle, as his thoughts and actions have been tempered by over a century of training within the Chapter's Librarium. He is a force to be reckoned with upon the battlefield, as he is able to twist and turn reality to his desires, and he shows a special gift for the Sanguinary discipline. Martellos also shares a bond with Captain Arenos Karlaen, as the two have fought side by side many times before. As a result he is often seconded to the First Company, where Karlaen values the Epistolary's wise council and the havoc he can wreak in battle.
Martellos later took part in the Cryptus Campaign and defended the invaded Imperium world Asphodex.
