The Elder Scrolls III: Tribunal - Plot

Plot

Once Tribunal is installed, the plot will start after the player first goes to sleep. The player will be attacked by an assassin, who is later revealed to be a member of the Dark Brotherhood, an assassin's guild that spans Tamriel. To find out more about the Dark Brotherhood, the player will be sent to Mournhold—the capital of Morrowind. Once in Mournhold, the player will have to locate the head of the Dark Brotherhood and complete a series of side quests for the new King Helseth and the Living God Almalexia.

After the completion of one of the side quests, a group of mechanical creatures called Fabricants suddenly attacks Plaza Brindisi Dorom. The creatures emerge from the statue in the middle of the plaza, and after their attack a secret passageway to Dwemer ruins is revealed. Since the creatures are mechanical, it is suspected that the secretive god Sotha Sil is behind this attack. The player then has to investigate the ruins and complete a few more side quests, in order to reconstruct Nerevar's lost sword called Trueflame. Upon acquiring the sword, the player is sent into Clockwork City in order to kill Sotha Sil.

This is possible because the storyline takes place after the events of the main plot of Morrowind, and it is assumed that the Heart of Lorkhan has already been destroyed, thus rendering all the living gods mortal. The player continues to explore all the rooms of Clockwork City, finally arriving to find Sotha Sil dead. When the player tries to leave the room, Almalexia appears and alleges that she had killed Sotha Sil and instigated the attack in Mournhold, in order to gain more power and control over the citizens. It is also possible that Sotha Sil was long dead (as evidenced by his apparent decay), and that having been driven mad by the Heart of Lorkhan, she perceived Sotha Sil's silence as mockery. The player is then forced to kill her before returning to Mournhold.

As the player exits Almalexia's temple in Mournhold, the Daedric Prince Azura reveals that the Heart of Lorkhan drove Almalexia mad and made her hunger for more power, and that mere mortals cannot become gods without consequences. Throughout the later gameplay, only three NPCs are able to believe that Almalexia is really dead; all others will be unable to believe this story and will have a lower disposition if the player insists that this is true.

By destroying the Heart of Lorkhan and killing Almalexia, the player continues fulfilling the Nerevarine prophecies, in particular—the death of the Almsivi Tribunal.
