The Law of Probability (they/she) is an entity who came into existence in the early 100s CR. They claim to be a god, and while this is unsubstantiated, their powers are immense.
Emergence
They claim to have been created by the mortal understanding of new mathematical principles and probability, slowly forming a consciousness and personality over several decades. This was particularly curious given how the Fracture of the Weave had severed the connection of most of the Gods to material plane. Perhaps, given their scientific nature, it might be worth further scientific inquiry.
Powers
They are able to use mathematics to foresee and affect the future. They can quickly calculate dozens of different possibilities and how they might affect the people and world around them. Small changes are able to create large effects, and they are very well able to handle making these small changes.
