NiVesseth was an Anklene reddish-orange dragon living before the Age of Fire.
He was a Lavadome dragon, and took part at the Second Urlant War. He defected shortly after the conflict with AuRel and Irelia, to search for a different life out of the Empire. Before his defection, he wanted to be a poet, among the Anklenes.
It's not known the ultimate fate of NiVesseth after his defection. At the time of the Second Urlant War, he was growing attached to Irelia, but the dragonelle is known to have become mate of AuRel.
For some unknown reasons, NiVesseth distanced himself from the pair (having found another mate, having departed for different lands, or maybe he could also have been killed by an enemy).
