Very random question, but has the characters telepathic communication ever been touched upon? I'm curious about if there's a limit range to how far a person can speak telepathically to another.
For instance, if Fate is away on a mission in some far off world, would she still be able to speak telepathically to Nanoha/Erio/Caro etc?
I don't know if there's an actual answer to that, but just thought I'd ask.
