Quest Stages - MQ203 (Alduin's Wall)

StageObjective
10 Escort Esbern to Riverwood
I've gotten to the Blades loremaster Esbern ahead of the Thalmor. I hope he's as knowledgeable about dragons as Delphine promised.
20 Talk to Esbern
30 Gain entrance to Sky Haven Temple
40 Learn the secret of Alduin's Wall
60 I found the Blades loremaster Esbern and brought him to Riverwood to talk to Delphine. He believes that the secret to defeating Alduin will be revealed by Alduin's Wall, an artifact created by the ancient Blades. We need to go to Sky Haven Temple to find Alduin's Wall and see what it can tell us.

He believed that the secret to defeating Alduin would be revealed by Alduin's Wall, an artifact created by the ancient Blades. We went to the hidden Blades stronghold of Sky Haven Temple, and found Alduin's Wall inside. It showed that Alduin was defeated in the past by some kind of Shout.
