The Possibility Chalice (1990)

The race is on. Minions of the High Lords frantically scramble to collect the relics of power, while Storm Knights try to do the same in defense of Core Earth. One such Relic is the mysterious Possibility Chalice, a powerful eternity shard which has garnered the attention of four different High Lords, as well as an intrepid team of Storm Knights who seek to find it first.
The Cryptic Destiny Map revealed how to find the Chalice. Now the Storm Knights must journey into the watery depths of a sunken temple, through the wild fantasy countryside of Ayslish England, into the darkened keep of an evil sorcerer, and across the icy water of the North Sea in search of the elusive relic.
Enemies are everywhere. Deadly Nippon Tech robots, ancient aquatic horrors, demons, trolls, golems, viking warriors and a powerful Ayslish wizard all vie for the power of the Possibility Chalice. Who will get it first?
