Onostothorin

A Void-forged blade of fire; Onostothorin is essentially part of the Elemental Plane of Fire carved out using unimaginable power and bound to a stone sword whose integrity is maintained through a link to the Elemental Plane of Earth.

Onostothorin's power is also linked both to the Banesword of Alas and to Vellamni's sword of fire.

Onostothorin's current owner is a Mantonian Warrior Adventurer Lucian Albrecht and was given to him by the First Blademaster of Nentreneth. Lucian is also in possession of Onostothorin's Scabbard.

In practical terms Onostothorin is a huge, two-handed sword that is magically light and easy to handle and inflicts massive physical and fire damage. Although the entirety of the sword is surrounded by raging fire, its wielder and his clothing and carried items are immune to the flame.

Onostothorin is an item of great power, poorly understood by its current owner. The full extent of its energy is hinted at by the fact that it briefly powered the Great Seal of Aethleas. It was soul-bonded to Lucian by the Dragon Benethyarr after Lucian's soul was grievously wounded in a battle beneath Hightemple.

Three similar blades, bound to the other three elements, also exist. They are Elvondorjust, Sylerandyth, and Lunstorgorthin.
