Rezső Seress' Sheet Music for "Vége a Világnak"

Origin
Rezső Seress was a Hungarian composer and pianist, best known for his composition "Vége a Világnak", also known as the Hungarian Suicide Song. It was later popularised by László Jávor as "Szomorú Vasárnap", and by Billie Holiday as "Gloomy Sunday". It is infamous for being the apparent cause of several suicides throughout Hungary, and was thought to have been banned from several radio stations, including the BBC. Rezső Seress also committed suicide, 35 years after composing the song. Despite no solid link being made between the song and suicides, the sheer reputation of the song was enough to make the original sheet music an artifact.

Effects
Reading the sheet music will cause depression in the reader, which gradually grows until it completely consumes them, driving them to suicide. The effect is sped up greatly if the sheet music is read whilst playing the song, and if the song is finished, it is almost certain the player will immediately seek out a method of suicide.

Collection
In 2016, a small time musician in San Diego acquired the sheet music. He used it during a set at a bar, which was attended by Mark Monroe prior to becoming an agent. After finishing his performance of the song, the musician committed suicide using a knife from the bar. Mark was also affected by the sheet music whilst trying to work out what happened. Eventually, Myka Bering and Claudia Donovan entered the bar looking for an artifact, which Mark presented to them. This event was the catalyst for Mark joining the warehouse.
