No singular thing inspired this roleplay, nor did any one thing inspire the system of magic.

However, [url=http://typemoon.wikia.com/wiki/TYPE-MOON_Wiki]Type-Moon's Nasuverse[/url] does have quite a bit to do with Spellcraft and Magic, particularly [url=http://typemoon.wikia.com/wiki/Magecraft]Magecraft[/url]. I have a pretty long history with the universe as I've read the light novels, played the visual novels, watched the various anime and animated movies, and have been in a few roleplays involving it.

There is also a bit of Eastern mysticism involved, as well as classical alchemic sensibilities (Classical Elements of Earth, Wind, Fire, Water, and Aether; etc).

The plot and setting appear to be entirely of HangedMan's imagination, though.
