One of the First Heroes gifted items by Mordenkainen. She was an elf battalion commander from Vanakour, a city known for its prowess in battle. Vanakour was/is a hidden glade in the tops of the mountains. The glade is sacred, ruled over by three ancient beings that are the first and progenitors of elvenkind. Their names are unknown to all but the high council.
Her weapon was badass. It holds a Balor trapped inside of it.
