Sword of the North

A longsword of parrying +2 with runes all over it that was wielded by the zombie king in Quasqueton.
The runes are the symbols of various human, elven, and dwarven gods of the north, and perhaps even some that are unknown to all three races.
The sword refuses to attack or parry the blows of a person who believes devoutly in a northern god.
Wielded by Eluria.
Session: Diamond of the Zombie King.
