Preservation of Honor

In an effort to prevent the High Elves from recovering the stolen artifacts, Shadecaller ordered they be split between three of the enemy's champions. The champions are charged with guarding the artifacts until such time as they can be personally delivered to Malekith. The directive mentions where each of the guardians is stationed. The nearest one is the keeper of the Tethlean Tome, a large treatise on tactics written during the many wars of the Phoenix King. Throughout his many battles, Tethlis kept detailed records of his daily affairs and decisions. In addition to these entries, the Tome contains information on the artifacts of the great king that are honored by the High Elves. Time grows short. You must recover these artifacts before they are lost forever!

Shadecaller's Directive reveals the location of the nearest guardian, Lorenth Resvan. Defeat the sorcerer and recover the Tethlean Tome from his corpse. Read again from the Directive when you have recovered the Tome.
