Zelosian's Chine was an underwater mountain ridge situated amidst the Great Zelosi Sea on Zelos II. During the Day of the Sepulchral Night, when the tides in the sea were at their lowest, the ridge would be exposed to the surface.

In 196 BBY a shipwrecked merchant prince buried his treasure in caverns at the base of the seamount during one instance of the Day of the Sepulchral Night. In 4 ABY, during another such event, the bounty hunters Solum'ke and Diergu-Rea Duhnes'rd found the treasure, but were forced to abandon most of it when the cave began to refill with water and the beings who owned their charter betrayed them.
