The Guagenian Star Sea was a location in the Guagenian sector. When Lando Calrissian was made to take the Solstice Globe to the Galactic Empire as a tribute, he had to take it to the Guagenian Star Sea. Ultimately, with the help of Rinetta Gan and Zel Gris, Calrissian instead delivered the artifact to its home on Livno III. It shared its name with the Inner Rim planet Guagenia.
