Oh, and Gaia (I hate how Riordan misspells Gaia as Gaea and Chronos as Kronos, I don't think there are any copyrights on myths)
*buzz* Wrong. Gaea is the original spelling, while Gaia is more Americanized. Chronos and Kronos(/Cronos/Cronus/Kronus) are two separate beings... which Riordan got mixed up between, accidentally merging the two all-powerful beings into one entity.
