Alenka Baethalor

Alenka belonged to House Baethalor in ancient Valyria, renowned as the finest riders of wild dragons. Because of her pure blood and sufficient magic to withstand fire and tame dragons, Alenka was put to sleep after the fall of Valyria and protected for centuries by priestesses of the temple of R'hollor. She was awakened when Laena died, before Rhaenyra and Daemon were united.
Daemon met her a few days after Laena's death. He found her when she confronted Cannibal. Daemon saw her completely silver hair in long braids and her indigo eyes. Everything about her screamed Valyrian. Daemon asked her what house she belonged to, to which Alenka replied that she was a Baethalor. Completely obsessed with her lineage, Daemon demanded the truth, introducing himself as Daemon Targaryen. She told him the truth. He watched Cannibal receive orders in archaic High Valyrian, he looked at her and knew she possessed a Valyrian jewel. "Marry me," Daemon said, "I will protect you with my sword." This was purely for strategic reasons, but also because, for the first time in his life, he stood before his equal.
