New Otoh Gunga

New Otoh Gunga was the main and first gungan city built on Ohma-D'un during the moon colonization in 32 BBY.

History
When Boss Nass had to deal with Otoh Gunga's overpopulation, he decided to launch a great colonization project on Ohma-D'un. So he sent Obi-Wan Kenobi and the Queen of the Naboo to help and set up a stable ecosystem on the empty moon, and establish the new gungan city. It was built underwater, just like its namesake Otoh Gunga, made of many hydrostatic force field bubbles. In 22 BBY, the entire city's population was nearly killed by the deadly separatist swamp gas.
