The only way to Aleroth is by zeppelin, so talk to Sepp atop Champion Harbour in the Orobas Fjords to be transported there. Proceed north through Aleroth, up the elevator, and continue further north to find Augustus outside the Ministry in the Great Market district. Speak to him to be granted permission to use the nearby waypoint shrine to enter the Ministry (you can also mindread him to gain one stat point). While you're here, be sure to take the Dragon Skill Book from an upstairs desk (north side), and loot the upstairs chest (south side) for the Crystal Dragon Claws Piece.
