These are some of the places various species call home in the Infinite Divergence universe. While Disa is technically a moon of Diro, it is the size of Earth so I have included it in this list.
Earth - Home of Humans.
Trayalia - Home of Juvo.
Diro - Home of Dren
Disa - Moon of Diro. The Dren's main research facilities are here.
