Peering at gems allows the player to see a map of a given dungeon level; torches or light-casting spells are necessary to be able to see inside dungeons. There are three modes of travel in the game: on foot, horseback, and boat. Getting around on foot is slow and can often lead to monsters catching up to the player character.

At the beginning of the game, Exodus is terrorizing the land of Sosaria from his stronghold on the Isle of Fire. The player is summoned by Lord British to defeat Exodus, and embarks on a quest that takes him to the lost land of Ambrosia, to the depths of the dungeons of Sosaria to receive powerful magical branding marks and to find the mysterious Time Lord, and finally to the Isle
