Oblivion:A Dark Exile
These quests are given to you should you break one of the Five Tenets in the Dark Brotherhood. The Wrath of Sithis will attack you in your sleep - you must defeat it to be allowed to be readmitted into the Dark Brotherhood. Notably, it is impossible to run from the thing; it seems to attack you in your dreams. As you might guess, it's impossible to obtain this quest after you initiate The Purification.
There are three versions of the Wrath of Sithis, which are identical except for their health. All are similar to a Gloom Wraith, and share the Gloom Wraith's immunities to normal weapons, frost, and poison. They attack with spells (including Absorb Health and Frost Damage effects) and a unique Dagger of Discipline (Drain Health effect).
Note that if you are due to level up, sleeping while any of these quests are active will not give you a level.
 A Dark Exile
The first time you break a tenet, you will be given the quest A Dark Exile. The weakest version of the Wrath of Sithis (health=215) is sent to attack you. When you defeat it, you are readmitted to the Dark Brotherhood.
 Another Dark Exile
The second time you break a tenet, you will be given the quest Another Dark Exile. The intermediate version of the Wrath of Sithis (health=500) is sent to attack you. When you defeat it you are readmitted to the Dark Brotherhood.
 Eternal Exile
If you break a tenet a third time, you are given the quest Eternal Exile: you are permanently expelled from the Dark Brotherhood. You must still defeat the Wrath of Sithis the next time you go to sleep (this time the strongest version, health=700) but there is no reward for defeating it, and you cannot rejoin the Dark Brotherhood.
 Journal Entries
- Not all Journal Entries may appear in your journal; which entries appear and which entries do not depends on the manner in which the quest is done.
- Stages are not always in order of progress. This is usually the case with quests that have multiple possible outcomes or quests where certain tasks may be done in random order.
- If an entry is marked as "Finishes Quest" it means the quest disappears from the Active Quest list, but you may still receive new entries for that quest.
- On the PC, it is possible to use the console to advance through the quest by entering
setstage DarkExile, DarkExile2, DarkExile3 stage, where
stageis the number of the stage you wish to complete. It is not possible to un-complete (i.e. go back) quest stages. See SetStage for more information.
