It was a stone. It was not a pretty stone, at first glance. Rough, about palm sized. Nothing special. Not until one looked more closely and saw that the stone's roughness had nothing to do with nature and everything to do with tiny runes painstakingly etched into its surface. That wasn't all, though. Did a young rogueling hold this stone in his hand, the stone would twitch, a tiny but distinct movement in a particular direction. He had been told what the stone would do and doubtless he is meant to follow its urging.
If he followed it, the stone would lead him in a direct path through the woods, stopping its movement only when he reached a small clearing. There was nothing particularly special about this clearing, save the small fire hidden in a depression and the scarred teenager sitting cross-legged beside it.
