5 Days after the guildhouse is built and if the quest "Rebuilding the Past" is finished, Rakis will visit the museum with a gift.
The Dev Aveza, the airship that will be docked behind the Explorers guild.
Inside the ship are a few crafting stations and sorted storage containers that are linked up with the Museums safe-house.
On the table is a manual how to use the ship and a map with markers that can be used to fast travel. These markers can also be used to fast travel to previously unknown locations, like directly into the Pale Pass area from Shattered Legacy.
