- ↑ Pandora was discovered in 'the late 21st century' ie 2050 at the earliest, and Polyphemus two decades beforehand (in 2030 at the earliest), according to Avatar: The Game's Pandorapedia. The first landings on Pandora were in 2084, so allowing time for travel it was discovered in 2077 at the latest, providing us with a latest-possible discovery for Polyphemus in 2057.
