Un

The Impossible Black Star of Un, or simply Un, is a strange celestial object located in the center of the Guild Expanse, in the Milky Way Galaxy. A truly gargantuan hypergiant star, Un is renowned for possessing many physical properties that defy all known laws of physics and nature. Un is not bright white or red, like most large stars. Owing to its name, it is completely black in coloration, similar in appearance to a black hole. However, it does not possess an abnormally-strong gravity well. In fact, its gravity appears to be perfectly attuned so as to allow for its single orbiting planet, Nexuta, to have a perfectly circular orbit, occasionally shifting so as to balance the movement of the planet. These characteristics suggest that Un is not a natural occurrence, but rather the work of some unfathomably powerful alien race. However, no civilizations known to exist, both inside and outside The Cluster, take any responsibility for Un's creation, leading to even more confusion concerning its origins. For some unknown reason, all Vuokra are terrified by Un's existence, and prefer to stay as far away from the star as possible.
