Powerful Beings

Powerful Beings is the name given to a particular kind of creature. Its not a species or a race, and they dont have that much in common with each other, outside of one specific characteristic: they have the power to greatly modify Universes, be it the one they reside in, or another one entirely. The way their power works varies greatly from being to being, but it always has great universe-altering results. They can be incredibly dangerous if malicious, but they can also be a great help. Their existence is unknown to most people, and their true nature is hidden even to those who know about these creatures.
