Sage
Sage was a young healer looking to aid novice packs when he came across Marble. The strange wolf spoke of superstition that Sage had no belief of, but he found their ways kind and innocent enough. He joined the Moontouched, promising to heal their members and follow their rules in return for herbs to experiment with and shelter. Sage went along and spoke nothing of his skepticism.
Things went normally in his eyes. He chalked up good hunting under the moon to coincidence, the "strength" wolves gained merely some sort of placebo effect. Admittedly Sage did not know how Marble could name everyone she came across, but it wasn't anything unexplainable. Perhaps she just listened to news and descriptions of travelling wolves from other animals? Nothing supernatural about that...
It was suspicious though. Curiosity peaked Sage decided to keep an eye on Marble, hoping for an explanation. .
