The void is the space outside of the wheel, the Aurbis. It is the outside space. This is where new realms are made. It might be where the et'Ada came from, but more than likely they originated in Aetherius (except for Lorkhan). Some say the daedra came from there, but I personally don't think so because prior to the Plan, et'Ada were all the same thing, but that's personal preference. The Void is the realm of Sithis and is Padomay.
