About the name
Eon is Greek aiōn, an age or a lifetime, and in later philosophy the whole of unbounded time — the word behind aeon and, through Gnostic usage, a class of divine beings. Geology borrowed it for the largest unit it has.
It is not a traditional given name in any language, which makes it a coinage rather than a revival, and it should be treated as one. There is a separate Welsh Eoin and Irish Eoghan that sound nothing like it.
Two open syllables, no short form needed. Pairs with two or three (Eon Gabriel, Eon Amara). On our vibe map it is Modern Minimalist with a Celestial reach.
