A tenebrous is a type of mineman who explains things that everyone already knows. He is commonly known for the following things, hacking (in 2007), being a professional explanor, and lastly exposing hypixel helpers for not knowing the obvious.

John had stayed in his room for days, scrawling tenebrous sentences like ''the darkness is coming. Nobody is safe from it. The world will never be the same again.'' He was later found dead, supposedly having committed suicide.
