Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.

“It
is often said that mathematics is the language scientists use to
describe the Universe. How is it that mathematics can change the
Universe? Can words that describe an object, make that very same object
change or move? No matter how much one can describe a car with words,
those words won’t make that car move faster, or change into a rock.
Or doing magic the high-tech way. In this version of the Pentacle of Power (see Nemesis rulebook) the amateurish chalk sketch is replaced with a homemade optical bench and properly calibrated beam-splitter rig and five prisms, upgrading the original student seance antics to full-blown functionality. The operator also needs a jar labelled Dust from ye Tombe of ye Mummy (prop. Winchester Road Crematorium).
