Fuegan

Fuegan, Phoenix Lord of the Fire Dragons, was thought lost when the Shrine of Asur was destroyed by the Fallen Phoenix, then he was seen on Medusa V with a retinue of fire dragon Exarches in an imperial fuel distribution centre. It is said he will reappear to fight alongside the Eldar at Haranshemash (which translates as "The World of Blood and Tears"). It is said in the last stanza of the Asuryata, the legend of the Phoenix Lords, known in full only to the Bards of Twilight. This passage says that Fuegan will call all of the Phoenix Lords for the Rhana Dandra and he will be the last to die in that conflict that will result in the final death of the Eldar and their gods alike.
