Two Moons is shaped like a crescent moon. The swamplands at the centre is shrouded in mist rising to the sky. The arc of the island's shore is spangled with small, glowing lanterns at night while the centre lie dark.
The sweet scent of the swamp orchids in the Two Moons swamplands can be smelled from the water; as the Star of Deltora was nearing Two Moons and was embraced by the curved arms of land that is the crescent, Britta described in her mind the scent of the island as 'a mixture of spices, sodden earth and still, dank water, with the faintest trace of something almost unbearably rich and sweet.'
The name "Two Moons" is likely a reference to Two Moons' crescent moon shape and the fact that at night the real moon is reflected in the water around the island, making it look like twin moons.
