Lexicon Malos is a compilation of magical rituals used by the Stygian Sisterhood to conjure a number of ancient gods and demons to the world.
In the series[edit | edit source]
Backup[edit | edit source]
In Backup, the Stygian Sisterhood attempts an elaborate ploy to have the Lexicon Malos published, aware that its strength is not in the rituals it contains, but in the knowledge of the entities it describes; its publication should therefore bring power to the Sisterhood. Thanks to Thomas Raith's efforts, the plot ultimately fails.
