Within the walls of Sky Haven Temple, the party finds and fights Umbalmo and Elenwen, Emissaries of the Thalmor. More importantly, Sariel manages to acquire the Staff of Magnus; pried from the cold, dead hands of Elenwen. With the deaths of Elenwen and Umbalmo, and the retrieval of the staff, not only does Sariel gain something she's been seeking, but the Tome of Magnus seems to react, and more pages are filled in.
