Tales of Symphonia
Derris-Kharlan is a third world in Tales of Symphonia. The planet is a giant comet comprised mostly of mana and is said to once have been the home of the elves before arriving at the world of humans, where the elves moved, living together with the humans. Derris-Kharlan was a giant comet that came from the depths of space, bringing the elves and the Giant Kharlan Tree with it. When Martel Yggdrasill died at the end of the Kharlan War, Mithos Yggdrasill, Kratos Aurion, and Yuan Ka-Fai made Derris-Kharlan their main base for Cruxis and separated the world into the planets of Sylvarant and Tethe'alla, 4,000 years prior to the events of Tales of Symphonia.
With the help of the Eternal Sword, Derris-Kharlan is protected with a force field emitted from the legendary sword. With the aid of the force field, Derris-Kharlan is unaffected by both Sylvarant and Tethe'alla's gravity fields and also remains transparent to the people in both worlds below. The only way to reach Derris-Kharlan is via the Tower of Salvation. In Tales of Symphonia, Derris-Kharlan forever hangs in the sky high above the two parallel worlds, Sylvarant and Tethe'alla. When Lloyd Irving and his companions kill Remiel in order to save Colette Brunel, Kratos appears and informs them that it is too late, and that the angels of Cruxis will now take the Chosen of Mana to Derris-Kharlan as a vessel for Martel. This is the first time Derris-Kharlan is mentioned. Later, it is explained by Yuan that Derris-Kharlan is Cruxis's main base, where they are plotting the revival of Martel.
