Howling Griffons

Howling Griffons
A Codex chapter who traces their origin from the Ultramarines. Their colour scheme is a quartered red and yellow design, with a griffon as their symbol. They are loyalist veterans of the Badab War and saw extensive action in the 13th Black Crusade, fighting against Chaos Plague Marines in the defence of Amistel Majoris.

For millennia, the Howling Griffons had a rancorous hatred of the warband of the Daemon Prince Periclitor, formerly of the Night Lords Legion, who slew their Chapter Master Orlando Furioso and the entire First Company on the 5000th anniversary of the chapter's creation. During the 13th Black Crusade however, the current Chapter Master Alvaro diverted his Battle Barge "Force of Destiny" from the war effort to pursue the Daemon Prince. Revenge was finally obtained when Periclitor was banished at the height of a titanic space battle between the Howling Griffons First Company and the Chosen of the Daemon Prince.

In the novel, Chapter War by Ben Counter, it is said that Lord Mercaeno, Chief Librarian of the Howling Griffons took Periclitor's head with his force axe. Lord Mercaeno subsequently fell in a boarding action of the Soul Drinkers' primary vessel.
