Rostrow

The Rostrows were an advanced humanoid race possessing bald heads and pointed ears. A Rostrow space mission led by Lahk gathered plant specimens from the planet Birr, but afterwards found that their ship was unable to take off. Lahk captured the Doctor, who had just arrived on the planet, and asked him to help repair their ship. He soon discovered that the Rostrows had mistakenly taken some of the native Verdants prisoner, unaware that they were intelligent beings, and the other Verdants were using a force field to prevent the ship from leaving. He and the Rostrow engineer Duh went to see the Verdants' leader Phlege and make peace with them. After the misunderstanding was resolved, the Rostrows were allowed to leave. (DWA: Mission for Duh)
