WalkthroughEdit

The Dragonborn will find From-Deepest-Fathoms wandering around Riften docks. Upon first meeting her, she seems despondent and paranoid, immediately handing the Lexicon to the player and pleading with him / her to return it to the Dwemer ruins of Avanchnzel.

Upon arriving at Avanchnzel, four transparent orange figures will be standing at the bottom of the big open room. These are the 'ghosts' of four adventurers (or "thieves", in their own words), who went to Avanchnzel to recover/steal the Lexicon. They will reappear throughout the quest and the Dragonborn can overhear that the two human characters had little knowledge about the place or item of interest, but From-Deepest-Fathoms and the Argonian male were very familiar with both and persuaded them to stay and complete the job against their better judgement. The two human mercenaries stay, only because the job paid well, but it becomes clear that the Argonians sought out the Lexicon for the knowledge it housed.

As the quest progresses, the Dragonborn will find the dead bodies of three adventurers, meaning only From-Deepest-Fathoms made it out alive. At the end of the dungeon, the Dragonborn will find the Receptacle in which to place the Lexicon. The receptacle for the Lexicon is guarded by a Dwarven Centurion. For a higher-level character, the guard is a Dwarven Centurion Master.

Upon activating the receptacle, the Lexicon will be removed from the player's inventory and open. The Dragonborn will be rewarded with Ancient Knowledge, a permanent bonus. The Quest will now be completed.

This dungeon is not accessible before the quest has been activated (Dungeon Lock Outs).

NotesEdit

• From-Deepest-Fathoms is not marked as an essential character so she can be killed if attacked. The Lexicon will still be in her inventory after she dies.
• Stealing the Lexicon only results in From-Deepest-Fathoms turning around and talking as if the Dragonborn has done her a favor and beginning the quest.
• From-Deepest-Fathoms will give the Lexicon to the Dragonborn even if he/she is in the water and not on the docks.

BugsEdit

• [360] Not necessarily a bug, but occasionally, when swimming near the docks in Riften, you will be adressed by From-Deepest-Fathoms, who irritatedly asks why you are bothering her. However, in the subtitles, her name only shows up as Fathom.
• The Ancient Knowledge perk is currently bugged; The armor bonus does not only apply to Dwarven Armor, but enhances armor rating from ALL heavy AND light armor types, rather than to only dwarven armor; This commonly leads to the assumption that the effect doesn't work at all, since the way one expects to see the change of the armor bonus is by comparing armor rating before and after equipping different armors – this assumption is incorrect because the armor bonus is still applied, even if it isn't applied correctly. In addition, instead of increasing the rate at which the Smithing skill increases, it increases the Smithing skill by 15 points.(PATCHED)
  • This information needs some attention. On my version (first patch, PC) effect is working as intended, at least dwarven part. Increases armor values of all types of dwarven armor by roughly 25%, both equipped and not. Doesn't increase armor values of any other types of armor. Smithing part needs confirmation.
    • Smithing value does not increase by 15 points as of patch 1.4 on PC. Current smithing value did not increase above 64 after completing quest.
  • Does not increase armor values on other types of armor (PS3)
  • This is not a bug but rather a fix that was introduced later, the boost to smithing experience will be missed but the bonus to tempering armor and weapons is welcomed with open arms.
  • Smithing value does not increase, but rather the ability to smith 15% better weapons and armor (e.g. armor that can be smithed with 100 rating, can now be smithed at 115)
• There is a rare chance that in the Avanchnzel Boilery's first ghost encounter, From-Deepest-Fathoms will not say the last line in the conversation and the ghosts do not vanish. When the next few ghosts appear, they do not say or do anything and stay put. This does not affect the quest, but it's also interesting to note that the Dwarven Centurion ghosts show up as enemies on the compass and the real Centurion cannot walk through them.
