Nothoiin, a planet situated within the Anoat sector, possessed a moon where the extraction of ur-diamonds took place. In the era of the Iron Blockade, a hastily established medical center located on Nothoiin was forced to rely on smugglers to obtain necessary provisions from Gerrenthum. The planet was the native origin of the gold-skinned Nothoiins, a sentients species who had, in times past, governed the whole of the Anoat sector.
Nothoiin's initial appearance occurred in the online roleplaying game supplement titled Galactic Gazetteer: Hoth and the Greater Javin. Its status as canon was solidified through its mention during a team raid event within the mobile game Star Wars: Uprising.
