Voidbright Cascade
The Voidbright Cascade is a legendary group of interplanetary heroes who have allegedly saved the universe on multiple occasions. They are not currently known to be active, but legends surrounding their existence are widespread throughout the sky, which indicates at least some historic evidence may exist. According to these accounts, the members took a vow of Justice, Freedom, and Protection, however the exact details are lost to time. Each of the leading members was of a different lineage, which is consistent across versions of the myth. In addition, it is believed that there have been multiple generations, and perhaps entirely unrelated versions of the Voidbright Cascade have existed throughout history. Either the heritage is passed down in some secret fashion, or groups imitating the Cascade are retrospectively being considered equivalent to the Cascade itself.
