THE VOLAR SYSTEM

There are 5 planets in the Vol (VOHL) system, Veek (VIK), Hool (HUL), Paart (PA ART), Seey (SIY), and Lahaart (LA-HART), plus one brown-dwarf Kaal (KA ALL), in order from Vol.

SYSTEM EVOLUTION

The Vol system hasn't always looked like this, it once were rather similar in structure to our own. With Veek and Seey being very similar to Jupiter and Saturn in appearance.

Moons and other minor objects aren't shown for simplicity

But due Veek's interaction with Seey in the early days of the system, things ended up more truncated into a 10 AU space, because of this turbulent period - Hool is in the Venus Zone, Paart has a massive moon, and Lahaart has a lot of them which every now and then falls into the planet and gives it a ring system.

The green area marks the progression of Vol's Habitable Zone as it ages

In the current configuration Paart is expected to remain within Vol's habitable zone for more 6,14Gyr, enough time for it's in-world life-cycle to take place.
