Jewels of Darkness: Adventure Quest (1982)

The sequel to Colossal Adventure is an interactive fiction game with a VERB NOUN interface. The fantasy setting takes a clear influence from Lord of the Rings. After centuries of harmony, Middle Earth has hit problems due to a cataclysmic sequence of events - a crop failure leading to animals turning violent, and then an attack from a mysterious enemy to the north. The evil Demon Lord Alagiarept is discovered to be responsible, and as such the Wizards are given a week to beat him, before Middle Earth must surrender. You play a rookie magician with Meditation, Mysticism and Moneymaking skills. While the main war goes on, you attempt a much bolder mission - locate the four Stones-of-the-Elements and the Medallion of Life to enter Alagiarept's Dark Tower and kill him.
