First is Therin, a super-earth with an incredibly dense carbon dioxide atmosphere, orbiting at 0.14 AU.

Second is a binary system comprised of Tuvi, a small habitable world, and Nykka, a smaller body roughly as large as the Moon. The pair orbits at about 0.471 AU from Sykra.

Third is Mialle, an Earth-size body with a nitrogen atmosphere and frozen lakes of water, orbiting at about 0.802 AU.
