Esbern reverts to historical scholar. As he examines the frieze wall, he explains that it tells the story of Alduin's time of dragon rule, the human rebellion led by those who could "shout," and finally a panel that shows Alduin defeated by a Shout. Esbern fears that only this Shout will defeat Alduin. Delphine isn't pleased about involving theGreybeards at High Hrothgar but agrees that you will have to return to them and ask to learn that Shout.

what comes up when you talk with the greybears? cause this part is supposed to lead you to learning clear skies to get to paarthenax.
