Ultima™ Underworld 1+2 (1992)

You are the Avatar, the most noble of heroes. In your day, you have beheld many wonders and proved yourself master of many dungeons. But nothing in your experience prepared you for this: the terror-filled passages of Britannia’s underworld. In this epic adventure you, the Avatar, join the leaders of Britannia in Lord British’s castle for an evening of celebration to commemorate the defeat of the Guardian’s forces a year ago. Suddenly, the Guardian strikes again, encasing the building in a gigantic blackrock gem. He offers the imprisoned heroes a simple choice: proclaim him ruler of all Britannia, or starve while his minions conquer the land. Can you free Lord British and save Britannia?
