Trella (The Monsters of Gokroth)

Trella was the leader of a village on Gokroth and warned about the monsters. She wanted to have someone help free her people from the monster. She chose the Seventh Doctor to defeat the monsters rather than Varron. She was attacked by Gor when he disabled her transmitter. She worked out that the monsters and her kind were of the same kind.
