ゲーム The Bard's Tale

The following text from the box cover summarizes the premise:

Long ago, when magic still prevailed, the evil wizard Mangar the Dark threatened a small but harmonious country town called Skara Brae. Evil creatures oozed into Skara Brae and joined his shadow domain. Mangar froze the surrounding lands with a spell of Eternal Winter, totally isolating Skara Brae from any possible help. Then, one night the town militiamen all disappeared. The future of Skara Brae hung in the balance. And who was left to resist? Only a handful of unproven young Warriors, junior Magic Users, a couple of Bards barely old enough to drink, and some out of work Rogues. You are there. You are the leader of this ragtag group of freedom fighters. Luckily you have a Bard with you to sing your glories, if you survive. For this is the stuff of legends. And so the story begins...
