Everburning Longsword

The Everburning Longsword was a magical longsword, presumably gifted to Thorak Fireaxe by the Burning Knight.

Appearance
The Everburning Longsword was clearly of demonic make, and flames constantly erupted from the blade. These flames could not be dispelled, although a sheath could temporarily block them.

Properties
Due to the flames erupting from the blade, the Everburning Longsword emitted bright light in a 40-foot radius and dim light for an additional 40 feet. The flames also dealt extra fire damage to the blade's targets. Killing a creature with any part of the sword would open a portal to the Abyss, summoning a lieutenant of the demon lord Alzrius.

History
It is unknown if the Everburning Longsword had a history before being given to Thorak or if it was created specifically for the orc leader. During his time as leader of the Fireaxe Clan, Thorak used the sword to perform ritual sacrifices in order to summon the Burning Knight. During these summonings, Thorak received advice and gifts of demonic supporters from the Knight. When cornered by the Pog Champions and Othurk's followers, Thorak killed himself with the Everburning Longsword in order to unleash the Burning Knight on his enemies.

When the confrontation with the Knight ended, the remaining Pog Champions took the sword from Thorak's body, immediately recognizing the need to destroy the blade. Soon, they were advised by Kain Thessos to travel to Atemcester and find someone who could seal the sword inside a demiplane. Kain was also able to commission a magical sheath for it, so that the flames and heat would not harm the other contents of the party's Bag of Holding. The party was able to keep the sword secure during their journey, hiding it along with other sensitive belongings during their stint in Magmaslag Rock. When they finally reached Atemcester, the Pog Champions were able to gain an audience with the Circle of Eight, where they were able to request assistance in sealing the sword. One of the archmages, using the name Zalos, offered to simply destroy the Everburning Longsword in front of his colleagues and the party. He cast a powerful spell, creating black tears above and incredible amount of pressure above the sword. When the spell ended, no trace of the Everburning Longsword remained and the blade has presumably been completely destroyed.
