Beneath the surface of Lake Paonga lies the Gungan capital. Otoh Gunga is constructed in such a manner that leaves the Gungan city trapped beneath water pressures—potentially fatal to the denizens should the city be breached—converging on the lake’s vertical center and floating between the surface of the lake and the lakebed. Its location makes the capital difficult to find without knowing its precise location, remaining untouched during the Separatist occupation of Naboo.

Water-breathing species would be able to swim easily to its bubble-shaped buildings; however, those unable to remain submerged without air would find the distance impossible to swim. Therefore, breathing apparatuses are essential for those determined to make the journey themselves and without the aid of Gungan bongos. Its bubble-like buildings are hydrostatic force-fields that contain breathable atmospheres for their occupants and have special portals that allow the inhabitants to enter and exit. Since the Gungans actually grew the building material of their cities from the natural plasma of Naboo and bubble wort extract, the structure of Otoh Gunga is a hub and spoke design. Each of the bubble-like buildings are compartmentalized units, able to be sealed off at a moment’s notice.

The Gungan Grand Army utilizes patrols that make regular visits between the compartments. Favouring spears, atlatls, Electropoles and cestas for throwing boomas, these soldiers are the staunch defenders of Otoh Gunga. Sometimes armed with distributed Gungan personal energy shields capable of turning aside blaster bolts, these warriors are too-often underestimated, lending to their victories over the Trade Federation.
