Im trying to get dragoncrypt traveler for traveler achievement but I cant get the quest for Lair of the Fallen. Bought a forgotten crypt key from the loyalist lady, went to talk to Tierna Morganna, she goes through her text alright, but doesnt give me the quest and I get the error "The way is blocked to you. Perhaps you would be able to enter if there was a reason to come here". Is there a trick or workaround? Tried giving her the key but she just hands it back.
