At the time of the colony there existed an indigenous man named cantuna. He was a good construction worker and therefore was hired to make the atrium of San Francisco church.
But as much as he wanted to deliver it on time, he was not going to be able to deliver it on time because it was a very huge amount of work. On the last night before the deadline a strange man, came up to him and told him he was the devil and that we would finish the build for him for his soul.
so the devil finished the work but he the mans soul because their was a stone that saved him and the building was finished on time.
