The slight commotion in the galaxy of the Ancient Heavens was the beginning of everything.
This galaxy was the mother galaxy of the Watcher, and there were two extremely habitable Gaia planets inside: the Heavenly Throne and the Temple of the Sky. Most of the Watcher's population lived here.
It was also one of the Holy Lands of many idealistic civilizations, but the Watcher themselves did not agree with such a statement. The only holy lands they recognized were the Emerald Tomb, the Walled Garden, and the Pure Treasure.
However, this didn't affect many people from the idealist civilization from coming to this star system for a pilgrimage.
The first civilization to know about the unusual movements of the Watchers was their vassal civilization.
Similar to the Voyager, they would occasionally improve the native civilizations, teach the natives, and guide the natives to walk the path of ideals.
