Zeppelin escort is the final mission in Divinity 2: Flames of Vengeance. In it, you must defend a zeppelin, in your dragon form.

In dragon form you get level 15 fire breath and fireball and level 5 in all other dragon skills (except Dragon Polymorph). You also receive 2 new abilities: Zeppelin Bombardment and the Eye of the Patriarch. You have to escort the zeppelin through the Black Ring Armada to the castle where you must fight Ygerna as the final boss.
