Aztec

The three pure white wolves stood across the river, one stepped forward. "You heard the alpha. Leave." They growled, I stayed where I was. "I'm already gone, you can't attack me for being outside your territory." I snapped back, putting a paw on the river that marked Moon Stone packs territory. "The alpha wouldn't allow it, but they're not here." The wolf growled, taking another step forward.

===========================================

Aztec is a somewhat unique wolf. He was born in the Arctic, meant to have a white pelt like his pack mates. Instead he was born with a black one. His pack thinks it's a curse, having a black pelt in the Arctic makes everything hard. His pack keeps him only till he's a colt, when he can fend for himself.

The Moon Stone pack? They're made out of entirely white wolves, they have quite a reputation. Everyone thinks they're perfect, they look up to them, and they plan to keep it that way.
