The Power of Kroll

Written by Robert Holmes

"Well, I've had a happy life. Can't complain. Nearly seven hundred and sixty. Not a bad age"

Searching for the fifth segment of the Key to Time, the tracer leads the TARDIS to treacherous swamps on the third moon of the planet Delta Magna. The Doctor and Romana soon uncover a plot to wipe out the Swampies, the local inhabitants, by the duplicitous crew of a gas refinery. Meanwhile, a massive creature is stirring beneath the waters, and the primitive Swampies believe the only way to calm the powerful monster is human sacrifice.
