Entity: Starlit Sentinel

Source Tian Xia Character Guide pg. 94

Though the zodiac is known throughout Tian Xia for subtly watching over the continent, sometimes the 12 constellations find more direct action necessary. When a grave threat arises, a zodiac constellation might shine on an everyday student or worker, granting them the power to transform into a powerful alter ego to repel those threats. Though most of these starlit sentinels act covertly when the world is asleep, some become well known either as urban legends or outright celebrities, though usually only as their alter ego. Some might find themselves pulled between the dual pressures of an unassuming civilian identity working in a market by day, and the defender of that same market from rampaging oni or qi-stealing jiang-shi under the light of the stars. Due to a quartet of well-known female sentinels operating out of Goka, many have come to believe that the zodiac chooses only girls as its champions, but the heavens care little for such mortal concerns and are equally likely to grant their power to those of any gender. Starlit sentinels are rare, even in Tian Xia, and individual sentinels are unique; a new sentinel empowered by a given constellation won’t awaken as long as the previous sentinel of that constellation is active.
