Yes, yes we have, someone already suggested that. Nothing. We're holding out on the magical presence idea, though, and trying to figure out if letting out the power would work.
I'm not sure if you know what I'm suggesting. A magical presence would try to block you from detecting it, correct? As well as any influence that would stop you from being able to reach something? Well instead of searching all occupied space in your brain, look for unusual pockets of nothing, and then investigate those empty pockets.
