Basically, you have a magic notebook in which you can write any word and that object will appear. And it can be anything - from boats and planes and trains to ketchup, turmeric, potato chips, fans, vampires, Cthulhu, swords, guns, gunmen, villains, superheros, medics, doctors, nurses, civilians, soldiers, Indians, cowboys, devils, demons, werewolves, telephone operators, shavers, bottles, water, snow, snowstorms, rainstorms, hailstorms, sun, moon, stars, etc. etc. etc. etc.

Literally anything.

Though not literally, since as I mentioned I seem to keep finding things not included. But maybe that's just me with my non-standard vocabulary.

You then use these items in combination with each other (and apply adjectives to them, of which there is also an impressive list) to accomplish tasks and obtain MacGuffins called Starites.

Or, alternatively, you use these items in combination with each other and with various adjectives to hold epic battles between a God, Giant God, Humongous Evil God, Good Cthulhu, Monstrous Devil, and Giant Invisible Vampiric Badger.

Your choice, really.
