Some more information on The Triumvirate System: (thanks goes to Jounin for the name!)
The star at its center will have 3 different names, according to what planet we're roleplaying a character on as it would make sense the inhabitants would each have their own name for it.
Drorthans would call the star "Sol, The Giver of Life".
Auvians would call it "Shara, The Nurturing Mother".
Otrarans would call it "Ra, The Bright One".
In addition to the solar system's sun, each planet has names for their respective moon or moons, depending on how many they have.
Drorth has 2 moons, each one the size of our own moon named Sila and Dar.
Auvis has one large moon, double the size of our own moon named Nue. (pronounced Noo-ay)
Otrara has 3 moons, two of which are half the size of our own moon while the third is about 3/4 the size of ours. They are called Lula, Lor and Iaria.
One more tidbit, in case it wasn't already obvious. Drorth is nearest to their sun, followed by Auvis, with Otrara being the farthest away.
Hopefully this helps to broaden the scope for each one.
