Grandfather, yes, but we have the Elysian problem. If Atlas is in fact properly spelt, then Atlesian/Atlysian makes no sense, since the adjectival form is Atlantian, and it'd be weird to change a vowel when one creates an adjectival form, and we have a possibly spurious second entity, presumably Elysium, which confuses things.

If, however, Atlas is spelt Atlys, then they're free to come up with an adjectival form, which likely would be ''Atlysian. ''

On reflection, I now think the latter is more likely, but we still have a problem, and need to get official spellings, to avoid the Vecchia/Vacuo confusion of old.
