PATH: Blade
DISCIPLINE: Barbarian

From official UXO.ea.com Website:

The barbarian is a warrior bursting with rage, an aggressive brute that attacks wildly and with utter disregard for his own safety. The barbarian cares little for defense in battle, preferring to strike hard and disable his foe before he can retaliate. He strives only to kill his enemy immediately and at all costs, and in his fervor he can actually gain strength from the wounds he sustains.

Also, since the Barbarian Discipline was never a part of the traditional Fellowship classes of Ultima IV, very little is know about their background. However, they are considered a Class in Ultima III, where it is revealed that they can use ALL Weapons, Leather Armor, NO Magic, and some Steal and Disarm Abilities. Once we have more details about this discipline, we will let you know.
