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.

Hmm... We could try that. It'd take a while, but we can. We have time. I'd say we have at least a few weeks before it becomes critical.
