Atlantcus

Atlantcus is a fictional archipelago and setting used in literature, games, and speculative media. Imagined as a maritime civilization located in the mid-Atlantic, Atlantcus is distinct from the legendary Atlantis and appears in a range of genres.

The archipelago comprises several large islands and numerous islets, with climates that range from temperate to subtropical. Major settlements are described as harbor towns centered around a lagoon city, built on coral reefs and volcanic outcrops.

In most depictions, Atlantcus emerged in late prehistoric times and developed advanced seafaring, engineering, and astronomical knowledge. Its decline is often attributed to environmental shifts, economic disruption, or sustained isolation, rather than a single catastrophic event.

The culture emphasizes craftsmanship, navigation, and guild networks. The economy is portrayed as reliant on maritime trade, sustainable fishing, metallurgy, and renewable energy, including tidal power and solar collectors installed on offshore platforms.

As a fiction setting, Atlantcus has appeared in novels, tabletop role-playing games, and digital storytelling. It is frequently used to explore themes of resilience, cultural exchange, and the interaction between technology and the environment.
