Arthelion is a binary star system of a A9 V White Main Sequence Star and its close companion K2 V Orange Main Sequence Star. It possesses nine planets, all of which have been heavily developed by the system’s inhabitants. The middle three planets are all sprawling ecumenolopi. City-planets of bronze, gold, and some ivory-like material. The inner planets all seem to be advanced farms to feed them, while the outer planets are extensive mining operations to provide the rest of the system with essential materials. All planets sport elegant orbital rings, from which serpentine space craft travel back and forth. A large spherical orbital structure is likely a starliner, though it looks as if disengaging it from the capitol world’s orbital ring would be quite a feat.
