I believe it's pronounced similarly to the Greek goddess/mother earth
GAIA (
Pavlos would be more familiar with the Greek word for earth, but I believe it's
Gaia, not
KAIA, but I'm sure he'd correct me if I am.) The way I explain the pronunciation of
Gaia is by splitting it into its syllables (GUY-ah) so
Kaia I'm sure is just a different beginning consonant sound.
Phyllis (aka Sidhe Uaine or
Gaia Euphoria)
