Serpent Moon is an adventure published by Chaosium in 1995 for the short-lived role-playing game Nephilim .
In Serpent Moon, the Nephilim (the player characters) must stop the Templars, who intend to exploit an astrological convergence.
Chaosium only published one adventure for it, releasing Serpent Moon a full year after Nephilim's publication.
[2] In Issue 6 of the UK magazine Arcane, Andrew Rilstone remarked "a Nephilim campaign turns out to be a little like supercharged Call of Cthulhu session - investigations, clues, secret cults and earth-shattering rituals.
This makes the book hard work to read and demanding to run but, in the hands of a good referee with a feel for the Nephilim universe, potentially very rewarding to play."
