Sure.
First off leme post this old pic of the items called the "Shards of Starlight"
I've since changed it to purely the center "medallion" with each two sections that are divided by the starburst pattern being one of the Shards.

Should look like the Medallions in LoZ: OoT in a sense, minus the spirit one.
Anyway from the top piece clockwise, each one represents the following systems:
Helios
Celestora
Egale
Venion
Sol Incineron
And the center is Nexion
If you know LoZ: OoT then ya could figure out what each color represents as well.
Anyway to the specifics for Venion and Sol Inceneron
Venion is the system seldom visited. The realm of Erebos, Keeper of the Threshold of Chaos. Rumors are that most of the planets are homes for monsters and demons. However, the planet that Erebos has built the Manor of Ethereal Night, Nox, has a vast city which is actually prosperous under the guidance of Erebos. Although the people seem to be Human, some of them are actually the last surviving pure Arcains, however Erebos has them go as Humans and therefore, the truth has been suppressed. The large majority are Human Sub-Arcains. Near the Manor of Ethereal Night, the Temple of Light and Shadow exists where Arcain Priests keep the secrets of Venturia safe. Beyond these borders are Demonarcs, creatures of shadow that are there more so to protect the Temple from outsiders.
Sol Inceneron is the system which the majority of its planets are almost deemed uninhabitable, yet the underground caverns of those planets are home for many people. Typically outcasts find their way to these planets to escape whatever they may be running from, or to simply hide. Typically thugs and gangs become prominent in the more mineral rich planets. The outer planets of the system actually bear some life and natural vegetation and are dominated by rocky terrain. Any water on these outer rim planets is underground.
Ancient Temples also can be found through out many of the planets, most of them have been abandoned and picked through by bandits.
