Great Void Technique

"Uh! There's an old-looking palace over there. Is this where the energy you're feeling is coming from?", a voice asked thoughtfully while studying the old-looking palace on the right path on an intersection that was giving off an ancient vibe.

'No, it's still some distance away. But we should check this place out, it might probably have something good', a smaller voice replied, only, the voice sounded in the head of the first speaker.

The duo speaking is none other than Grey and Void.

Grey had his hand on his chin while he was scrutinizing the palace calmly with Void laying on his shoulder as always.
