The Lagoon

The Lagoon was a community of renegade undersea computer technicians on the planet of Dac. They became known for solving problems in an unorthodox manner as well as challenging social conventions. Tendaar Bel was active with them instead of attending class at Coral Collegium until the takeover of the planet in 19 BBY.

Behind the scenes
The Lagoon is mentioned in Tendaar Bel's Character Folio included with Fantasy Flight Games' 2014 roleplaying game Star Wars: Age of Rebellion Beginner Game.
