Wool

You are hiding under a table after a horrendous attack by the demonic teachers who lost their temper due to the poor grades and decided to cause a massacre where very few survived. The institute was giant so it seemed like a labyrinth with no end, like a large liminal space. In the bloodstained hallways and the dim light of the remaining energy, (wool) came walking nervously, scared and tense. H-hello?? -- is anyone alive??? Please.
