History
The Thanatosian Tomes were forbidden books about forbidden cults and dark gods,[1] Shuma-Gorath and the Old Ones.[2]
They were translated by 1623 by the Marquis de Rais.
By the Modern Age, the Thanatosian Tomes were known to magic users as a "forbidden" and "hellish" volume, and a "dark chronicle".
Those books could be found in the local library of Starkesboro, and were seemingly studied by Doctor Strange under the Ancient One's tutelage.[1]
Content[]
The Thanatosian Tomes recounted information on cosmic obscenity that slumber and on the cults and lost races trying to end that slumber.
Notes
- The Thanatosian Tomes are presumably inspired by books of ancient knowledge and horrors created within the Cthulhu Mythos, such as the Necronomicon, the Celeano Fragment, Nameless Cults or the Pnakotic Manuscripts, among others.
