Kuyuk

"It isn't a familiar's place to ask questions about the Rayek." Kuyuk is a Red Dragon spirit made of thunder and lightning. In human form, he is quite calm and relaxed without being lazy or indifferent but as a dragon, he is a ferocious beast. He was Akitsek's familiar before Makhai came around, during the Era of Legends.

He acts as something akin to a mentor towards Makhai when he first becomes a spirit.

Though not a Rayek himself, he has a status quite near them, as he is in charge of Thunder and Lightning due to being a Sūhai. He is allowed to sit in on the Rayek Counsels if he pleases.

Kuyuk is an excellent example of a Sūhai who is heavily disconnected from their animal spirit, having a near entirely human mind.

Appearance
In his human form, Kuyuk has the appearance of a man with long blond-coloured hair, some of which is tied in a knot on the back of his head.

He also, in his human form, has a red dragon tattoo all along his left arm and hand.

Personality
Kuyuk is a taciturn and formal individual who is thoroughly concerned with fulfilling his orders. A capable and perceptive individual and familiar, he is willing to follow any of Akitsek's orders. His personal reasons for being loyal to Darya are never fully explained in the story, but his devotion is unquestionable.

He is shown to worry about Akitsek, and Makhai to a slight degree, as he shares some words of concern with Koschei.

In his dragon form, Kuyuk is notably different in character and has cruel and merciless tendencies.
