One planet. Ten eras. Every age remakes the world.

CEOS is an original dark fantasy / sci-fi universe built across myths, wars, civilizations, archives and endings.

The project began as personal worldbuilding notes in 1995, with digital files developed since 2012. Today, CEOS exists as a large evolving archive of stories, characters, eras, maps, images and worldbuilding materials.

This page hosts free archive packs, stories, character cards, concept art and selected materials from the CEOS project.

Created from Polish-language lore and developed for international readers, with English as the main global front and selected future language editions.

The project uses an AI-assisted creative workflow: visuals, translations, layouts and production assets are created with multiple AI tools under human direction, editing and canon control.

Current release line: CEOS Archive Pack 001 — Sahir & Vaelira

Original lore. Long-running archive. AI-assisted production.
