Intro: The quest for the fifth segment of the key of time takes our intrepid adventurers to the third moon of Delta Magna where they will find themselves immersed in a feud that will eventually bring them to the awesome reality of "The Power of Kroll."

Outro: Next week, the search for the final segment of the key to time will take The Doctor and Romana to the twin planets of Atrios and Zeos, and a full-scale interplanetary nuclear war. Be with us next Sunday evening at 11 for "The Armageddon Factor." [source: ChicagoEpguides]
