The Legend of the Chainman

Back in the year 1500, the legend of the beggar who made the chains that surround the Velez Chapel in the Cathedral of Murcia is told. The Marquis of Velez had him imprisoned, tearing out his eyes and hands so that he would never again create such a wonder. Nothing more was ever heard of the Chainmaker. Until now… We have discovered the original Velez Chapel, where the chains were made. We need to find the material from which they were made, as this material is more valuable than any other known. You have less than 60 minutes to achieve it, over said Chapel weighs the terrible curse of the Chainmaker, who blinds and curses forever anyone who remains inside for more than an hour. Will you be able to discover the secret of the Chainmaker?
