In fact, the Three Gods already had plenty of magic-less worlds under their command.
The Three Gods had long since lost interest in such worlds.
They wouldn't conquer such worlds themselves, and They couldn't even be bothered to send Their Clans to do so. In fact, Their Clans were completely unaware of these planets, which simply ended up in the shared zone, visible only to the highest Authority Holders.
As for why eleven Demon Worlds appeared here with no Deities rushing to conquer them...
Well, there was a reason for that.
In short, it was undoubtedly due to the bizarre and peculiar nature of these worlds.
Take one of the Middle Demon Worlds, for example.
The entire world was a sea of shit.
Methane and swamp gas blanketed the entire world, plunging it into perpetual darkness. The stench was so overpowering it blotted out the sky.
The ruling Race was a species of shit-eaters, with appetites much like dung beetles.
