Amapsau Marsh is a large estuary fed by the water coming off the northern side of the Himalayas. Built in the trees of an old-growth forest on the marsh’s northwestern edge is the goblin city of Niloctus. The goblins of Niloctus rely on the marsh for their food and for special animal and plant products they export.
There is a hidden orchard within Amapsau Marsh that grows silver apples. This orchard is a twin to the golden apple orchard at the Pillars of Hercules in the west. The location of the orchard is a closely guarded secret of Nilcotus to ensure their valuable treasure is not stolen by others. In addition to having an obscure location the orchard is rumored to be guarded by a powerful monster.
