The Delver's Dirigible is one of the new mounts coming in The War Within, and with the most recent beta build, we can finally obtain this mount, and take a first look at it! Learn how to obtain it, as well as the customizations currently visible ingame.
You will obtain your Delver's Dirigible shortly after hitting level 80 in the War Within! Once you hit lv80, Brann Bronzebeard by the Delver's Headquarters in Dornogal will offer you a quest introducing you to the concept of Bountiful Delves.
Bountiful Delves are a special «affix» to Delves that do not increase their difficulty, but rather grant you extra rewards at the end, accessible via chests that you need Keys for. Bountiful Delves change every day, their map icon is changed to highlight the fact they're Bountiful for the day, and keys used to open the extra rewards are awarded from doing world content in the War Within.
The quest Bountiful Delves grants you your very first Restored Coffer Key and requires you to clear a Bountiful Delve at any difficulty tier.

Once completing this quest, Brann will give the following quest Ship It!, granting you the Delver's Dirigible! Below, we have a video of the mounting animation (currently the same as the Dragonriding drakes from Dragonflight) and the /mountspecial animation.
Customization for the Delver's Dirigible can be done in a Rostrum of Transformation, similar to the ones seen in Dragonflight — In Khaz Algar, there is one in Dornogal, located on the southwestern portion of the Forgegrounds. We have pictures of all Dirigible Customizations seen in-game below, but be mindful that because of the nature of Beta, these are very likely not final.
