The Sea of Translucency existed on the planet Dremulae, a world in space.
This particular sea drew in many tourists from across the galaxy, including those who might otherwise choose a simulated vacation, or sim-voyage, via holographic technology.
In the year 24 BBY, Astri Oddo, a Human, remarked that her spouse, Senator Bog Divinian, had stated his belief that he would soon have the financial means to acquire a villa in close proximity to the Sea of Translucency.
