Sword of Beowulf

The Sword of Beowulf is a magical weapon once wielded by the hero Beowulf.

Appearance
The Sword is a one-handed sword with a wide, double-edged and slightly leaf-shaped blade. It has a round cross-guard with a groove in it, and a spherical pommel, both made of a dark gray metal.

The scabbard is a gray humanoid arm (possibly the arm of Grendel) that clasps the cross-guard until the spell is spoken. Near the chape, it changes into a conventional scabbard.

Abilities
Only the pure of heart (either pure good or pure evil) could take the sword from its sheath and summon its power with the incantation "abannan afod Beowulf". At its full potential, it lit up gleaming orange, and was able to shoot deadly beams of energy.

Background in other media
The Sword of Beowulf is a unique concept for the series, and not easily identifiable with the legends of Beowulf. In the entire saga, he used four swords—his own, Unferth's Hrunting, a troll-sword from Grendel's mother's hoard, and Hrothgar's Nægling. All were destroyed, and none had apparent magical abilities.
