Half a dozen comets slowly make their way across the night sky in a tight formation. The tails of Iynn's Dependents are bright and intertwined in corkscrew pattern, cutting a brilliant and unmistakable path in front of the moons. Trapped in a complex gravitational relationship that astrologers do not fully understand, Iynn's Dependents constantly circle and bob around each other without losing any of its members. Despite coming within the orbit of Elanthia's moons every four years, both mathematics and foresight agree the massive comets will not collide with the planet. Probably.
Note: Visible around the Fourth of July (about every 4 IG years). Joke constellation.
