Eteiset

Could you clarify what eteiset refers to? I can’t locate a widely recognized real-world subject by that name. It could be:

- a botanical genus or species

- a mythological figure or term from Greek

- a place or geographical term

- a fictional concept or work of fiction

If you specify the context, I’ll write a concise, neutral, wiki-style article under 300 words. If you’d like, I can also provide a neutral stub for a fictional or hypothetical term.
