Well, maybe not a healer, but his shadows are kick butt at soothing pain. Call him... the anesthetist.
So, Garreth:
Name: Garreth Raund
Race: Human
Gender: male
Age: 46
Appearance:
http://severeene.deviantart.com/art/Viking-Warrior-20110376
Weapon: A sturdy broadsword, and Kozche's soul-forge bow. He is a master of both weapons and a fierce brawler.
Magic: A few little charms and amulets, the type you can buy in a market, not much else. (If he purchase a spell you'll know what it is in game- and it's nothing big.)
Personality: Gruff. He isn't heartless but he's a warrior, not a parent. He bears the dragons great hatred for the death of his family and takes this out mostly on Kozche, who he honestly believes is half Dragon. He might realize other-wise if he devoted any thought to it while he was sober.
Motivation: Pay for his next round (and to finance future hunts) and glory of the hunt. He doesn't have anything else to live for.
History: A hunter by trade, when his wife and son were killed by Dragons he turned to slaying them specifically. During the final years the Dragons plagued the lands he was sold a very young Kozche as a curiosity of sorts. He hates what he believes the boy to be, but being around the age of his own lost son he has trouble hating the child himself. Not that you'd notice.
Dammit here I was going for a basically 2-D character and I had to give him feelings. Blaaaaagh. I think I feel dirty.
