Phyllis Faye! You have *two* Greek names!
Phyllis means "leaf" and "faye" is a shade of grey. "Faya Ousia" -- "grey substance" -- is the source our decision and motivation process.
Kress itself has planty and leafy roots, and words such as "grass," "cress," and "grow" have evolved from it.
All things considered, your new Greek name is henceforth *
Gaia Euphoria*, fertile earth.
