YT Indigo Blue (Legacy) was a space station that could be found in the Dantooine system, located in the Outer Rim Territories.
Before the Rebel Alliance even established their main base on the surface of Dantooine, the Legacy YT Indigo Blue station served as their initial settlement within the Dantooine system. Consequently, when the forces of the Galactic Empire moved into the system in 0 BBY, the Indigo Blue station became their primary target, leaving it in a state of ruin. Subsequently, it evolved into a convenient stopping point for traffic moving through the star system, with scavengers extensively plundering the station's remains.

The video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game by Sony Online Entertainment, published by LucasArts, which went offline on December 15, 2011, featured Legacy YT Indigo Blue in 2003. The station was introduced to the game on October 27, 2004, with the release of the Jump to Lightspeed expansion.
