Scintilla

Scintilla is a red giant star in the Greenwater Nebula approximately 30 lightyears from Meruu. It is more than 170 times more luminous than Sol.

In the past, Scintilla most likely have more planets, but the most inner worlds likely got devoured when the star turned into a red giant.

Thanamort
A planet orbitting so close to its star, it is literally boiling away.

Vitam
Vitam is an orange gas giant with a faint ring system. It was mined for helium-3 since 2120 AD, but was abandoned in 2138 AD after an infestation of Squarglians on one of the moons.

Vitam II
Vitam II was formerly a planet with a methane-based biosphere on the surface several billion years ago. However, since Scintilla turned into a red giant, most of its original atmosphere has faded away leaving behind toxic conditions on the surface. The caverns below, however, sustain an extremophile biosphere just above a subsurface ocean of liquid water.

Yeren
An aquamarine ice giant planet that appears featureless. However, there are some tiny moons which appears to have carvings likely created by an ancient spacefaring race. There is no direct evidence as to who created these carvings.
