The earliest known civilization in Nadanan were the Cread, also known as The Builders. This civilization of sentient beings was known for its achievement of advanced magickal arts, at levels unmet by any other known civilization. Using their advanced knowledge, the Cread built portals to connect the Realms, and built a massive empire throughout much, if not all, of Nadanan.
Legends say that the Cread were also responsible for the creation of humanity, and many other sentient races that exist. Using the power of life-weaving, it is said that the Cread created other races to serve them in their empire.
Sometime after this, the Cread mysteriously dissapeared, and ceased to exist for unknown reasons.
