There is a yawning hunger in Darktail.
Smoke is cold and his father is absent and it soon teaches him that the only way to keep from caving in on himself entirely is to grasp at anything he can reach. It doesn't matter what. It doesn't matter who.
But the burn of emptiness becomes all the more painful as he gains more land, more power, more cats in his Kin, and it doesn't seem to go away. He pushes it at others, tries to force his burden on them, and it… falls short.
The fire rages hotter as he tangles with his father, claws out to shred him. Onestar stares at him, disbelieving, and all the more furious. Darktail feels himself tearing in half.
The fire cools when he is plunged into the lake.
