Vespers

Vespers is an interactive fiction game. It is set in a medieval monastery. A horrific plague has fell upon the land, and the abbot has made the difficult decision to shut the doors, denying the sick villagers sanctuary. However, the plague has still wormed its way inside the walls and now but a few monks remain alive. One particularly grim night, an exhausted girl comes to the threshold. Her arrival coincides with the beginning of horror, as mysterious deaths start among the remaining brethren. The abbot tries to get to the bottom of the mystery, even as his own life is in danger.

The puzzles in the game typically permit several different solutions (including the ability to pray to saints for help). Depending on the player's choices and conduct (moral or immoral) throughout the game, several endings are possible.
