Purchase a hippogryph ride to the Exodar from Laando. When you land, take Topher's List to Nurguni in the Seat of the Naaru at the Exodar.
For a small fee, you can rent one of my hippogryphs to fly you to the Exodar.
Taking the hippogryph is a faster, not to mention safer, alternative for someone carrying an important message. If you'd like to take a ride, speak to me again and I'll make the arrangements.
