This was definitely confusing you. You had been following the Path of Destruction for a while, but you were never informed of this odd mark.

On your lower midriff, there was the Path of Destruction symbol, almost marking you; like a tattoo. You couldn't seem to remove it, oddly enough.

Nanook was always watching over you. He was the Aeon of Destruction, after all. He needed to watch his followers. He placed the mark on you, because you were about to get... 'destroyed.'
