From publisher blurb: The Haunted Halls of Jarl Sigurd describe three northman-inspired classes for OSR games: the Hirdman (fighter), the Sea Raider (barbarian), and the Thurl (magic-user). An experienced GM can use this document to convert the class to any OSR system of their preference. However, the class was designed with the medieval-authentic system of Lion & Dragon and the setting of Dark Albion in mind.
