Lore

The head of Hell’s secret police ceaselessly reads minds, erases abilities, and spreads wrathful distrust.

Agaliarept, one of Hell’s most prominent demons, is inextricably bound to the blossoming of occult literature in the 18th and 19th centuries.

According to those texts, Agaliarept is no mere demon but one of six high officers directly beneath Lucifer and his prime minister, Lucifuge Rofocale. His first written appearances coincide with the rise of modern state bureaucracies and intelligence services, a link reflected in his role: he embodies infernal bureaucracy and investigative oversight. The Grimorium Verum claims he is one of Lucifer’s two chief aides, sharing authority with Satanachia.
