Lost Heaven

Lost Heaven, also known as Terra (テラ), is the name of a "lost land" in.

Background
Lost Heaven was first observed by people living on the Sciencia Sea through Star Shards. These star shards can be found at the place where a falling star has landed. Responding to the seven colours of light, these shards reveal the supposedly imaginary world known as Lost Heaven when projected with a set amount of light.

Praised for its dynamic nature with flora and fauna more beautiful than one has ever seen, with greenery all the way to its borders, Lost Heaven fascinated people across the Sciencia Sea. Unable to imagine that Lost Heaven is part of their own world, people have start to long and look for the imaginary Lost Heaven. One of these was astronomer William Herschel, who set out by ship to find Lost Heaven. He never returned.
