The night air was thick with moisture and bubbling thunder pierced the silence as Lena, Igor and Tom waited in the empty classroom for the storm to end. Everyone had long since left school, but they were to stay another hour for a physics project. Lena, impatient as usual, suggested a break: - 'Come on, let's go down to the old basement for some snacks,' she chuckled, pointing to the metal door leading under the stairs. They walked quietly, only the echo of their footsteps bouncing off the walls. Up close, the door seemed older than the whole school, rusty, with a strange symbol carved just below the handle.

Igor froze with his hand outstretched to the handle of the crate, and Tom dimmed the light, as if he hoped it would all stop then.
