Spellbreaker

It is Infocom's eighteenth game.

Over the course of events in the trilogy's earlier games from 956 to 957 GUE (Enchanter and Sorcerer), the player's character has progressed from a novice wizard possessing a few weak spells to the leader of the Circle of Enchanters.

Now, in 966 GUE (ten years after the events of Enchanter), the very foundations of Magic itself seem to be failing, and the leaders of all the Guilds in the land have gathered to demand answers.

In the midst of this impassioned meeting, the crowd is suddenly transformed into a group of toads and newts.

Everyone present is affected except for the player and a shadowy figure who flees the hall.
