Naesala is the King of the Raven Clan and isn't a really nice bird. He's from the same games as Soren and Reyson.
In Elyasia, Naesala is the leader of the northern Crow demon clan. He may not seen it, but he's really caring about the princess and his clan. Yet how he got the leader spot is unknown. Even if his father was the last leader before disappearing with the Heron race.
There are rumors saying that he was the one who ordered the death of the Heron race. Yet he's also childhood friends with Reyson, so the rumors are just rumors.
Naesala and his clan are really loyal to the rulers of the northern lands. Either Lyra nor her aunt mind the crows yet Lyra finds Naesala interesting. Much like her sister, Lyra had befriend the crow leader and called him her black bird.
His nickname given to him by Lady Lira is: Guilty Crow King
Reasons unknown but maybe Lira knows something about what he did or didn't do.
