Zendayr was the first elder dragon created by Kirrentyr and Zinnora, and their direct descendent. According to dragonkin legend, Zendayr oversaw the development of Aghera's first mortal races and served as their liaison with Zinnora and Kirrentyr. Zendayr also communicated with The One Who Lurks Beneath the Ice and the The Devouring Flame and ensured that the developing races did not earn their ire.
Zendayr followed Kirrentyr into battle with Zilmanok and the combined Abyssal armies, and is believed to have perished alongside him while buying some of the mortal armies time to retreat to safer shores.
