Return to Caregiver Chellan

If I remember correctly, Azure Watch's hippogryph master is Zaldaan. If you've spoken to him before, then you can take one of my hippogryphs to him. That's a good lesson to know: hippogryphs are always trained to fly to their capital city, but they'll only take you to a remote hippogryph master after you've already been there. Since you arrived on one of Zaldaan's hippogryphs, you can also use that route to return to Azure Watch with the caregiver's supplies.
