Singing Stones

Exploration Stage: Quiet Promenade
From: Alford Stone
Description: The prototype of the whistle is complete. All that remains is to tune it so that it can drive away the misty starlings. I brought a special stone for this purpose. Can you find a stone with a he clef and bring it to me?
Completed: If you tune your flute with this he clef stone, you will be able to speak with the birds in their language. What do you think we should tell them? "Go away, or I'll roast you whole!" Is this enough to get the message across?
