Warhammer 40k - 2013 Advent Calender Short Story - Marneus Calgar: Lord of Ultramar by Graham McNeill

In the aftermath of the Bloodborn invasion of Ultramar, Marneus Calgar meets with his Chief Librarian in the shadow of their primarch’s stasis-tomb. As they reflect upon the hardships of the past year and contemplate the future, both Tigurius and his Chapter Master realise that difficult decisions must be made – and a powerful enemy must be faced, lest Ultramar suffer greater losses still.
