Daishain’s 5e D&D RPG Character Creation The Cold Fury says...
Allow me to introduce you to Pol, son of Nels, from the Snow Leopard Clan. He is the last Snow Leopard, as the clan was wiped out by a rival clan. Pol was knocked out and left for dead during the raid. He only survived thanks to being found by a few Harpers who were on an assignment in the frozen wastes in the northern reaches of Faerun, near The Spine of the World. In thanks, he agreed to assist the Harpers and act as a guide. Since then, with no home to return to, he stayed with the Harpers and has become one of their specialists.
A strapping fellow of 6' 6", he tends to be boisterous and fun-loving, despite his tragic personal tale. When deep in his cups, if asked about it, he shrugs, and acknowledges the loss and grief, but understands that life is not fair, and death comes to all eventually. He does not burn for revenge, though if he does come across a member of those who killed his family and tribe, he will gladly offer a challenge. But he has found meaning in his new life with the Harpers. He enjoys fighting, "For the good of all. Especially my clan!"
So far I am leaning towards using the Outlander background, but I am always willing to adopt anything that assists the Dungeon Master in moving plots forward. He could be hunting someone, being hunted, in possession of something that he is unaware it being valuable to someone, a dead-ringer for someone else… let me know.
