Shadowlord

Shadowlord is a board game published by Parker Brothers in 1983. In it, two to four players, each representing a "master" of one of the four Greek elements (earth, fire, wind, and water) battle each other, and a non-player character called the Shadowlord, to become master of the universe.

The object is to destroy the armies of opponents, and of the shadows, before the timer runs out and the shadowlord wins and the game is over.

Below is a list of objects required to play the game and their purpose.

He ruled the galaxies of the Universe with wisdom and justice…and by powers the likes of which no man or woman has ever possessed. His name was the Starlord, and his word was Law. When he grew old, the Starlord created a beautiful and mysterious crystal which harnessed his wondrous powers so that they might be preserved for the Starlord’s five children. He called it the Power Stone.

When the Starlord’s death came to pass, into the Shadow Master’s hands fell the Power Stone. He became the Shadowlord, and a glorious civilization crumbled into darkness and decay.

If this civilization is to flourish again, one of the four remaining heirs must emerge as the Starlord’s successor. Who will it be…the Earth Master of Taurus, Virgo, and Capricorn? …The Air Master of Gemini, Libra, and Aquarius? …The Fire Master of Aries, Leo, and Sagittarius? …The Water Master of Cancer, Scorpio, and Pisces? Or will the Shadowlord overpower them all?
