Lands of Erdos
Weapon (longsword), artifact (requires attunement by a stregoni)
This sword was made shortly after the elfwar by a secret stregoni organization and was blessed by Theléa, the goddess of the drae. It was then gifted to House Von Redlore and it serves as the badge of office of the King of Eranhein.
Currently it is wielded by Prince Damian Von Redlore.
