Lantea

Lantea is a fictional planet in the Stargate franchise. It is portrayed as the ancestral homeworld of the Lanteans, a humanoid species descended from the Ancients (also called Alterans). In the series lore, the Lanteans are depicted as highly advanced, with a long tradition of exploration, stargate-based travel, and ascension to higher planes of existence. The planet is a recurring backdrop in the broader Stargate mythos and is referenced as the source of much Ancient technology recovered across the galaxy.

A central element associated with Lantea is the city Atlantis. Built by the Ancients/Lanteans in the Pegasus Galaxy, Atlantis becomes a major hub for exploration and defense against hostile forces after its discovery by teams traveling through the Stargate network. The connection between Lantea and Atlantis is a focal point in the franchise’s Atlantis storyline; the two worlds are linked by the reach of the Ancient civilization.

Technological and cultural achievements attributed to the Lanteans include advancements in power generation, Stargate technology, and practices related to ascension. The Lanteans’ legacy, through their ruins and artifacts, continues to influence civilizations encountered by SG-1 and other explorers within the Stargate universe.

In official media, Lantea is depicted as part of the franchise canon, with appearances in television series and related tie-in materials. The depiction varies across episodes and novels, but core elements emphasize its role as the homeworld of the Lanteans and the origin of Atlantis.
