- Find Tythis Nirith.
- Find clues to Nevena's Whereabouts (0/4).
- Find a Way Inside the Wakener's Hall.
- Defeat Wakener Maras.
- Take Nevera's Diary.
- Talk to Tythis.
After talking to him, you have to find clues about Nevena Tythis' whereabouts. Enter Drinith Ancestral Tomb where you'll find the first two clues. To find the first go right at the first crossing and it is on the right side. The second one is deeper in the tomb right before you enter the bigger chamber. After finding the first two clues, continue your way through the tomb into the Caverns of Kogoruhn. There, you will find the two remaining clues.
When you have collected all clues continue your way into the Forgotten Depths. The next task is to find a way into the Wakener's Hall. In front of the door you find six bells with Daedric runes in front of them, spelling the word "DREAMS." The same Daedric runes are on the wall surrounding the door behind the bells. The correct order is 1,2,4,3,6,5 (D-R-A-E-S-M).
Enter the Wakener's Hall and defeat the boss Wakener Maras. After dealing some damage, Nevena Tythis appears and attacks you as well. This fight can be rather difficult as Maras can fear the Vestige while Nevena uses Dragonknight abilities, so it's recommended to have enough Stamina available to break free and interrupt as needed. When you have defeated both enemies take the diary and return to Tythis.
