The Guagenian Star Sea existed within the Guagenian sector. As a tribute, Lando Calrissian was ordered to transport the Solstice Globe to the Galactic Empire; this required him to travel to the Guagenian Star Sea. However, with assistance from Rinetta Gan and Zel Gris, Calrissian instead brought the artifact back to its place of origin on Livno III. The sea's designation was the same as the Inner Rim planet called Guagenia.
