Nightshade, a character of mine.

He'd been plagued by strange, dark visions most of his life, and had been banished from his clan for (mistakenly) killing one of his littermates. The clan leader also gave him a nasty scar as a parting gift of sorts. Nightshade spent the rest of his life wandering, fighting, an eventually dying, all the time regretting what he had done to get him here.
