Oroborous

Oroborous is one of the most well-known CEmen. A running joke related to this user is his striking similarity to the Half-Life series protagonist Gordon Freeman. He is also known for being a math professor in Europe, and for being one of the older CEmen. It is known that his past was somewhat troubled, and frequently used narcotics (this may or may be a complete load, based on my memory).

His username is believed to be based on the Ouroboros, an ancient symbol depicting a serpent or dragon swallowing its own tail and forming a circle.
