The Merciless Catalog of Fiends, often simply abbreviated to the Merciless Catalog, is an enyclopedia detailing numerous evil extraplanar beings and the truenames which can be used to bind them.[1]
The Merciless Catalog is incomplete, and contains numerous errors. Shortly after its publication, several devils distributed fake copies with inaccurate information for their own truenames, but which left those of their rivals intact.
The Book of Vile Darkness is also believed to contain the truenames of powerful fiends. A similar text, Splendors Beyond the Veil, describes the truenames of powerful undead.
