The Legend of Torquemada

As history students, you have arrived in Spain for your summer practicum. Not far from your camp is the ancient Santa Cruz la Rial monastery. The monastery is famed for one of its disciples who later attained the title of the Grand Inquisitor of Spain - a fervent exterminator of heretics. History tells that the main reason for this young man's transformation into a bloodthirsty executioner was the mysterious disappearance of his biological father within the walls of this monastery. Several centuries have already passed since then, but no one ever found out what exactly happened. Locals still avoid this place to this day. However, this story intrigued you so much that no warnings could stop you, and you set out to explore the ruins.
