Tyranny of Dragons
The captain is a strong man with unusual black skin.
In battle, Othelstan wore splint mail and fought with a shield and flail. If forced to use ranged attacks, he would throw a spear.
Captain Othelstan was a member of the Cult of the Dragon who supervised the Cult-controlled village of Parnast in the Greypeak Mountains.
Othelstan controlled Parnast during the Tyranny of the Dragons when the mobile Skyreach Castle was just over the village. He briefly met with the Black Wyrmspeaker Rezmir when she arrived in the village in transit to the castle.
