Thranduil carefully walks down the corridor of whatever this strange building seems to be. There's pools of blood everywhere, blood spatters all over the walls, bloody handprints everywhere.
He doesn’t really know how he got here, one minute he was in his kingdom forest, the next he stepped into a weird looking storm and suddenly he woke up in a field, kids in uniforms trying to bite him, they were all covered in blood, snarling, growling, and making strange croaking noises and all their bones snapping.
Thranduil only just narrowly escaped them all by running into a building. Which of course, typically was filled with even more of those....things. But as he hid in one of the empty, after a few minutes of those things banging on the windows and doors...they all started screeching and running towards the exit.
Once he was sure it was quiet outside, he slowly opened the door and quietly walked out before heading down the corridor, watching the corridor, room and doors. Just as he was about to pass another room, a warm hand suddenly grabbed his arm and pulled him into the room and closed the door.
When Thranduil stumbled and looked up, he can see a bunch of teenagers in what looks to be some kind of school uniform, like the one's who were trying to kill him. They were all covered in blood and holding bats.
