Oh, good, he's sold it. Sora flicks up a thumb and, without much further ado, begins to walk backward out of the little circle of light. The flame in his lantern gutters a little, and he feels a little ill, but that's a normal lantern separation thing. He nods, takes a few more steps.

On step three, his foot lifts away from the snow, and there's black smoke rising from the footprint. Sora looks up at Soldat and nods. Fine. That's normal.

Another step. He begins to shiver. The light in his lantern dims even further, and black mist starts seeping from the ground right behind him. "I'm okay," Sora manages. His hands are shaking, his eyes are fluttering shut. His head tilts to the side as though he's suddenly lost equilibrium.

Another step. The shivering has rapidly progressed to a shake, his hands contorted and moving involuntarily. "Th-This is what happens, it's fine," he says, but it's slower, as though he's trying to pull his mouth into the right shapes. On the last word, a tendril of black smoke escapes his mouth.

The snow has disappeared under a slick pool of swirling darkness. "It's fine, it's fine," he repeats, teeth clacking, mouthfuls of darkness escaping and curling around his face. "It's fine, it-"

He stumbles as though he's missed a step off a sheer cliff, falls backward and disappears into the ground.
