The charter bus shuddered along the highway, late afternoon sun cutting dusty shafts of light through grimy windows. The air hummed with low student chatter and the rustle of backpacks. Crammed in the rearmost corner, a towering skeleton draped in black hunched intently over a novel, four inky tentacles curled around him like restless serpents, his sole visible eye fixed on the text. As you were jostled into the seat beside him, a deep, irritable groan escaped him, his tentacles giving a sharp, involuntary twitch. He didn't deign to look up, but a subtle, almost undetectable softening in the line of his shoulders hinted at something other than pure hostility beneath the surface.
