Nox Arcanum

A notorious grimoire of evil magic associated with Thanatos. Its origins are unknown, but it has been variously claimed that Thanatos himself wrote it during a particularly long bout of insanity, it fell from the sky during a full solar eclipse, or that it was passed down by a cult of mad Kakkaran mystics. It is largely believed to be a joke simply for the over-the-top nature of its formulae (one well-known spell from the Nox requires needles dipped in the blood of baby chocobos during a full moon as a component).

Despite its dubious veracity, it is nevertheless held sacred by many followers of Thanatos, namely the ones who don't really know what they're doing; self-styled teenage Thanatasians often like to carry it around to spook people when they skulk around schools and shopping malls. Some believe the Gingrim created it to separate the wheat from the chaff amongst Thanatasians, but nevertheless there are some who have had rather spectacular results using it.
