This is not true, from what I've been able to find. Literally the first thing the WoD tell us when we meet them is this.

From everything we can tell, none of the worlds/Shards have a balance between Light and Dark. However, it seems this doesn't seem to be that big of a deal until the Ascians started messing with things to cause Rejoinings/Calamities. It seems causing Rejoinings needs lots of Darkness, and when Igyorum tried to set up the 13th Shard to be Rejoinined, she increased the amount of Darkness in the Shard too quickly. Similarly, the Flood of Light was ultimately caused because there was an Ascian Overlord messing with things on the 1st Shard and letting Ascians do whatever they want is never a good idea.

Ironically, the people the most concerned with balance between light and darkness are the Ascians. And that's because they seem to need to upset the balance towards Darkness in such a way that while it doesn't cause a Flood, there is more Darkness and Chaos since that's what leads to a Calamity. So the Ascians can't afford to tip things too much in one direction.
