This is a picture of one of the characters in the Gotrek & Felix novels by William King set in the Warhammer universe. Troll Slayers are Dwarfs who are seeking to atone for past misdeeds by setting themselves against the most fierce of monsters in battle.   They're pretty decent novels, not high literature by any means, but decent sword & sorcery stuff.   There's just something appealing about a dwarf with a mohawk.
