Brimstone

This real time all-text tale puts you in the role of Sir Gawain, a knight of the Round Table. It takes place in a dream that traps you in the underworld of Ulro, where you must learn five magic words in order to escape. The most unusual aspect of this game is probably the perspective: the story is described in the third person, with Gawain referred to by name, unlike most other text adventures that use the second person, referring to your character as ‘he’.
