Somewhat of an oddball, Karstark keeps to himself most of the time. Usually found in the back of the lockerroom polishing his curiass or sharpening his knuckleblades, not many on the team wish to speak with him. However, what is known is that when he does speak, it is often to hurl accusations and insults, most usually at young Rob Stark, for perceived slights on the pitch. With the way he holds grudges, more than one fan has speculated there may be a drop or two of dwarven blood in him.

Unfortunately he took a savage blow in Game 16 from Cleaver. The team apothecary was already busy patching up the star player of the team, Eddard Stark, so Rickard was left to bleed out on the sidelines, his promising career cut short.
