Caelus (/kejləs/)

Caelus contains five major population centers (3 planets, 2 gas giant moons), numerous bases, multiple warp paths, a portal communication center, the political center for both the Grand Society and The Caelum, a trade and commerce center, a military center for The Caelum and nearby regions, a manufacturing center, an agriculture center, an entertainment center, two Phaseball teams, and three of the Five Crowns.

• Vecu — capital planet of The Caelum, political center of the Grand Society and the old Imperium (The Court), trade and commerce center, cultural center, entertainment center, Phaseball team, Prince of the Five Crowns
• Opis — planet, agriculture center, Princess of The Five Crowns
• Sethlans — planet, manufacturing center, Prince of The Five Crowns
• Bellona — moon, major military deployment and training center, elite military
• Portunus — moon, shipping and communication center, nearby portal

Caelus has the rare occurrence of three earth-like planets within its habitable zone. (Scholars speculate that the Ancients modified their orbital paths and possibly terraformed at least two of the planets. Another highly doubtful theory is that the Ancients actually constructed the planetary system out of the star's protoplanetary disk. Also, they still debate if the large gap between Girra and Boreas was caused by the existence of the portal.)

The main orbitals are:

• Girra, a greenhouse planet.
• Opis, the first habitable planet and its moon, Losna.
• Vecu, the second habitable planet and its moon, Manea.
• Sethlans, the third habitable planet and its moon, Bellona, the home of The Caelum's elite military training center.
• Aurae, an asteroid belt.
• Azag, a permafrost planet, conveniently located close to Porta Portal is mostly barren. Its moon, Portunus manages the system's shipping and communications, and oversees Porta Station.
• Boreas, a medium gas giant.
• Notus, a mini gas giant.

Several anomalies support the theory that some, or most, of the planetary orbits were adjusted. The main anomalies are:

• The existence of three planets within the habitable zone and closer together than typically found.
• Not only does Vecu have the same length of day as the Juridical Calendar, but the hours of the day are identical. Since the Juridical Calendar is based on The Great Star Storm and the Vecu Seasonal Calendar is based on the start of the first season after epochal event, it is highly unlikely these would match so perfectly.
• Girra's rotation is exactly three times longer than Vecu's rotation — highly unlikely to have occurred naturally.
