The Solleu River was a large river which ran through Naboo's capital city of Theed. Fed by underground tributaries that flowed from the planet core, Theed was mainly an island that rested in the rivers grasp. The mighty river, adored by both Gungans and the Naboo, ended in Theed at Virdugo Plunge, the largest waterfall in the city. The Funeral Temple crossed the river, which was incorporated into a tradition where the ashes of the dead would be deposited into the river.
