Chief Librarian Y'reles
Head
of the house of Librarians in the Legion, Y'reles is a powerful psyker
who is amongst the chapter's high council. He is the keeper of the
chapter's history and archives aboard their space fortress and he
decides who may enter the highly restricted Inner Librarium.
In battle Y'reles wields his powers in a way that strikes fear into the
hearts of all who oppose the Legion, conjuring images of death,
destruction and unbearable pain and implanting it into his enemies'
minds. All who look into his glowing white eyes run in terror as
they are cut down by the merciless Marines.
He is recorded in the long list of Heroes of the Imperium as managing
the great feat of having beaten an Eldar Farseer in pyschic combat, one
of very few Imperial warriors to ever do so. Though the battle
was draining on the Librarian, in the end it made him a stronger psyker
and earned a great deal of respect amongst his peers.
