The Lost Sword of Toledo is the fourth episode in the Agon adventure game series, rightly billed as a stand-alone game with new characters and original puzzles. The Lost Sword of Toledo has been given a range of additional features, including more detailed, manually animated characters, more realistic graphics with new 3D effects, and dialogue-orientated storytelling, while still retaining the features of the previous instalment; integrated, story-based puzzles, authentic surroundings and background music with local elements.
Central character Professor Samuel Hunt arrives in the picturesque Spanish city of Toledo, where time seems to slow down. He's intrigued by the narrow streets, squares with an atmosphere of the Middle Ages, the silence and calm. But does this peaceful atmosphere conceal some longstanding dark secrets? A young man, formerly known for his honesty, has recently been caught stealing treasures, and now some local families have renewed wounds of past grievances, the secrets of which have been taken to the grave. However, if the professor is to find the answers he seeks, he is compelled to unravel the entangled threads. Professor Hunt finds a mysterious music box, an iron door in the church which has not been opened for 100 years, and a series of strange letters. But will the Lost Sword of Toledo be found?
