Evocati

The Evocati were a specialised formation of the Ultramarines Legion during the Great Crusade and opening days of the Horus Heresy during the mid-30th and early 31st Millennia. They were comprised of several thousand Astartes drawn from a dozen Chapters, awarded the highest honour of all: overseeing the operation of the XIII Legion's War World Armatura and the training of new recruits, commanding an Imperial fleet to rival any other.
