Infernum is a Polish black metal band founded in 1992 in Wrocław by Grzegorz Jurgielewicz (also known as "Anextiomarus" and "Karcharoth") and Tom Balrog playing also in Oppressor and, at present, in Baphomet's Throne.
Several months later, another demo entitled, Damned Majesty, was produced with the help of a keyboardist Robert Fudali (pseudonym Rob Darken) from the band Graveland.
In 1994, the band released their debut album entitled Taur – Nu – Fuin, which was published by Astral Wings Records.
Before the split, however, Infernum recorded a demo entitled When the Light Has Died including three new songs without vocals or the keyboards.
According to Rob Darken, Jurgielewicz became an informant to the Polish authorities, who were exerting pressure on various individuals connected with black metal groups and nationalist ideologies.
