Sahandrian

Sahandrian was the longsword of Corellon Larethian, the god of elves. Rumored to have been forged from the heart of a star, Corellon wielded Sahandrian throughout the Elf Wars and in many of his battles against Gruumsh. In the year 2959, Corellon gave Sahandrian to the Brightstone Heroes for use in a ritual to seal a portal to the Far Realm. The dragonborn Elytra took the sword with her through the portal, where she thrust it into the aberrant being known as Allabar and completed the ritual; though the portal was sealed, Sahandrian was destroyed in the process.
