The Euphoric Insanity is a disease that first emerged in the Erenite city of Ocham in Y9614*, characterized by a mental state of blissful peace, denial of negative events and circumstances, and a sense of reckless abandon in the search of pleasure and leisure.
The Euphoric Insanity appeared while Erenon was already suffering from mass outbreaks of the Restone Plague. Communities where both the Euphoric Insanity and Restone Plague were present were quickly annihilated, as citizens mingled and partied seemingly unaware of their imminent deaths.
The Euphoric Insanity is known to still exist, with rare flare ups within Erenon. It is not fatal alone and usually passes on its own even without treatment within a short time, as long as those infected don’t blissfully take an action that places them in grave harm before this time.
