Skygate

The Skygate is the large dark object the Three Suns pass in front of and disappear behind throughout the year. No one knows exactly what it is. Some believe it to be another world like Aroka that the suns orbit. Others saw it as a the gate through which the Three Suns suns emerge from and into as they travel to and from the void throughout the year. There are even those that believe it to be a great creature or being and that the suns are also great beings that protect it or maybe even ensure it can't break free and destroy Aroka.
