In this Void, the brothers Anu (stasis) and Padomay (change) appeared.
This Void is the name applied to the dimensions outside of the known realms of Aurbis, the Universe. Though the details vary with each culture and religion, all legends of the beginning of existence which have been passed down speak of two entities who appeared in the Void and soon found themselves in conflict. Here's a selection from the first chapter. I've been writing a big huge document of all the lore I could find, starting from the beginning (which is a bigger problem than you might think sources are contradictory, especially The Annotated Anuad is ridiculously unreliable - I've had to write a separate appendix on it). Your question is a bit vague, so info dump incoming.
