The knights of Camelot vs the Patrons of the Norse Gods.  While Albion's may have higher armor factors, the Midgards can truly dish out some amazing damage.  Both caster classess are mostly balanced, but the true difference is with the fighters.  Highlanders may hit more often then the slow cumbersome troll, but the troll needs alot less hits to dispatch its foes.  This battle takes place within the Hibernia Emain.  Monster encounters are almost nil, and roaming guards are generally not in the areas.  If not for the long hike there, this would be the optimal dueling place for all realms.  However things may change depending on what people want.
