I got the misc. quest before joining the DB, and never did it until after I was done with their questline.
So I can get the flute just fine, but when I go to find Pantea there is no quest marker and she's totally disappeared.. I figured it was a glitch and reloaded a 3 hr old save to find out that it wasn't.
Turns out she was at Vici's wedding and Veezara likely killed her in the chaos, since I found a coffin with a key to the Bards' College inside the Solitude Catacombs.
Wack.
