Shinryu, the Worm God.

[Dualblade]

While correct, "wyrm" would never refer to a lowly earth worm and more readily connote a dragon or serpent. On the other hand "worm" is more readily associated with slimy invertebrates in your garden.

Funnily enough I didn't bat an eye to this due to another game that uses Worm when talking about some very powerful beings that have yet to be seen, which with some other info in the game highly suggests they actually are dragons.
