There was, in fact, a Rune close by, and as you release your hopeful song to the heavens, you feel a pull to your right - toward the side of the mountain. How curious! As you draw closer, you feel a resonating hum through the stone as something blue began to glow beneath a small pile of snow on the ground. With a brush of your paw you swipe it away to reveal a perfectly preserved Rune, pulsing merrily as if delighted to be found.
And then you hear a crack.
A short fissure opens up behind you, and you can see another wolf approaching swiftly, small and golden; the ground gives way, and you have to scrabble to keep from slipping down into its glowing depths.
But the Rune is fine, at least.
