What is the definition of Tevnia?

Tevnia is a peculiar blend of the Greek word 'teva' meaning 'darkness' and the Finnish suffix '-nia' implying a place or being. So, picture this: "The Tevnia of existential dread was so dark it made my cat go into a permanent purr-fect mood!"

Now, for an edgy example: "As I stared into the Tevnia of my own inaction, I felt the chill of cosmic indifference seep through my skull and summoned a black hole of self-doubt, which promptly devoured my last chocolate cookie."
