Etsojin is a non player character in the Landscape campaign.
He is approximately seven feet tall with red scales (marking him of a higher status than other chromatic dragonborn, and beneath only silver and gold dragonborn in caste).
In the episode What Are You? Colourblind?! Johann devastatingly maimed Etsojin by shooting an arrow into his eye socket at close range. Etsojin escaped, and has not yet been heard from again.
