The Claymores successfully engaged and destroyed the ISD Wrathful in the battle for Caldania, though no-one is quite sure how.

While destroying the ISD several bombers slipped past and levelled many of the major cities on Caldania. The handful of Claymores remaining were trapped by the sudden arrival of the SSD Executor, though with the timely intervention of the Alliance Frigate Regis of Red Squadron, Granite managed to escape. Granite joined the Alliance and served as part of Red in such actions as the battle with the Triumviterate Fleet and the Heritage Affair, being promoted to Training Officer and terrorizing innocent cadets with his bagpipes until he left to join White Training Wing aboard the Joan d'Arc, where his talents were put to especially good use within and out of the Armoury. Granite recently resigned his commission with White Squadron and moved on to Wolfshead Squadron aboard the Wolf's Den.

The most obvious parts of Granite's personality are his deadly temper and his extreme aggression. While considerably smaller in stature than most pilots, Granite has often been known to intimidate beings twice his size. Granite is always prepared for a fight, sometimes to the extent of simply going looking for one. Extremely loyal to those he knows well, Granite is just as deadly to those he hates. He likes suicide runs and watching things blow up dramatically. It has been hinted that Granite has a quieter side shown in his small pet hamster, Hobbes. This is usually from people who do not realized that, while cuter, Hobbes is just as dangerous as Granite.

Granite normally flies the Slayn & Korpil B-Wing, although he also owns a heavily modified (lots of extra weapons) Skipray Blastboat named the Bannockburn. His preferred weapon is his Duralinium-plated chainsaw, along with a few hundred others (and the scary thing is, he's proficient with almost all of them). His preferred drink is Caldanian single malt whisky.
