Upsilon

Upsilon is a philosophical concept of fickle presence. Many are unknowing of Upsilon. Many are happy. The ideal itself is best known from a story, written by your typical pretentious drunk brit, titled Upsilon dies backwards. The story has themes of hope, and wonder at the storm raging around us, forever omnipresent in our universe, but the actual essence of Upsilon has a far more... chilling exterior. 

A rogue researcher of the Progressiverooms traveled into an unknown level, barely escaping with his life into Level 0, but it's believed that in that level was the rogue cosmic entity, Upsilon. Upon viewing Upsilon, in all of its majesty, powerful, and unknowing Upsilon, and no one comes to visit, the researcher's mind was destroyed, putting him into a catatonic state, simply due to the vastness of the world. The knowledge of Upsilon today is now regarded as a sort of cognitohazard, although no one can truly know how it works. Rotting away in a research facility, is the only human vessel that knows of Upsilon's true form, the name of said vessel is lost to time, and all of their research is long gone. All we now know, is that no one comes to visit.

Upsilon is best friends with The Barman
