Xanthan

Xathan was located inside the Delphic Expanse and homeworld to the Xathani. Due being covered by 94% water, most of its cities are gigantic floating centers, made up of hundreds of independent platforms. Capital to the  Xathan Trade Order,  it was conquered in 2005 by Unified Kingdom of Inkaara to keep the planet from joining the Second Xindi Empire and later became a full member state of the nation.
