Unfathomable Depths is a side quest given to you by an Argonian named From-Deepest-Fathoms. She can be found on the docks near the Riften Fishery outside the gates of Riften.

Objective

• Take the Lexicon to Avanchnzel

Walkthrough

The Argonian gives you the Lexicon and asks you to take it to Avanchnzel.

Enter Avanchnzel. (Tip: Before entering you may want to stock up on lockpicks - there are many, many, locked areas and chests in this dungeon, and some really great loot to be had). Follow the straight path and you'll also encounter some specters, probably showing what happened in the past. Make your way to the bottom level where you'll find the door leading to the Avanchnzel Animoncultory. Continue pushing forward as the area is straightforward. There's a Racial Phylogeny (+Restoration) skill book inside one of the rooms along the way; just be careful of the spinning blades that will spring up from the floor and mortally damage you.

Continue pushing forward until you find the next door leading to the Avanchnzel Boilery. Continue along the path until you reach the last chamber with the Lexicon receptacle. The standing Dwarven Centurion Master will come to life and attack you. Defeat it and finally place the Lexicon on the receptacle to complete this quest. You can also avoid the Centurion Master, place the Lexicon on the receptacle, then head for the door and close it behind you.

Upon completion you recieve an active effect called Ancient Knowledge. This gives you a 25% bonus when wearing Dwarven Armor and Blacksmithing increases 15% faster.
