The Dev Aveza is given to you by Rakis five days after completing the quest It Belongs in a Museum. Rakis will come to the Museum in the Dev Aveza and gift it to the player. If the Special Edition is installed, Rakis will instead meet the player outside the guild house to give them the Staff of Indarys. A Thalmor agent will then attempt to assassinate him. If Rakis is killed, the ship will remain for the player to use. Alternatively, if the player stops the Thalmor agent from assassinating Rakis, he will gift them the Dev Aveza as thanks.
The Dev Aveza acts as a movable player home. In the Classic Edition, there is a manual next to the fast-travel map on the first floor inside the ship. In order to fast-travel, set a location and go back outside. Activating the steering wheel will move you and the ship to your chosen location.
The second level offers armor and weapon racks as well as crafting material chests that are all linked up to your safe-house storage. Anything deposited in the safe-house is also available from these chests. If Picky's Resonator is obtained, it can be installed into the Dev Aveza engine.
There is a smuggler's hold under hidden board covered by a rug on the bottom floor. Inside are two chests and Sanamia's Journal. If Moonpath to Elsweyr is not installed, the Thrassian Plaguesword and Kordir's Skooma will also be found there.
