Death cause: Leadership challenged by Aldrag - Lost the fight.
A hot headed young blood that ambitiously ventured unknown territories in order to start his own dynasty. Though impulsive he's got the smarts and the guts to become a leader and hopes to see his pack grow greater with each generation.
To insiders: Grizzly is all about the growth of his pack, every action is set with a purpose and optimized to benefit the whole group. If a wolf is of no use he's more likely to get rid of them and rarely tolerate "useless mouths to feed." Though if you work well enough you will get what one could join for: Food, protection and a roof to sleep under. In simplier words, he makes sure everyone's well and fed as long as they're of use to him.
To outsiders: The pack is always looking for strong wolves to land a paw and help it expend. Though they're quite territorial and seemingly agressive when they first approach they'll accept anyone who they deem worthy, if not they'll chase the intruder or even put them down if they have to. Getting in is already a though task now staying inside the pack is another story. Grizzly makes sure to assert his clan's strenght and presence by marking the territory rigorously either by scratching, urinating or howling. So if you hear chants coming from the Moaning Highlands think twice before stepping in.
