Everyone in Dolanaar is so proud of Sister Aquinne. I'm certain she'll be pleased to receive this thoughtful gift from Nyoma.
When you're ready to travel to Darnassus, just speak to me again and for a few coins, you can hire a hippogryph to take you there. I'm told Sister Aquinne enjoys the solitude of a small plaza just south of the hippogryph master in Darnassus. Look for her there after you arrive.
