Tarper (Eclipse)

Tarper was one of the original colonists on Pteran and now lead the colony. She didn't believe the Eighth Doctor's story. She was harvesting the tree sap to make a fortune. It kept her young, but she joined the telepathic field of the trees as a consequence. Because she drunk enough of it, the Hellstrung caused her to metamorphise into the tree she damaged.
