Labyrinth of the Mind

From publisher blurb: Mensageiros são enviados para atestar a sanidade de um mago, o que pode dar errado? Rumors begin to circulate that the magician of the kingdom is losing his lucidity. As he renders services to royalty, his presence is summoned from time to time, but in the last month he only responded to calls with an incomprehensible letter. The royalty has come to consider him useless, ignoring him, but a noble is concerned and intends to visit his tower to better understand what is happening to the mind of such a powerful and wise individual. A small group of his trust was requested to accompany him on this journey, as if rumors are confirmed a mad mage is something quite dangerous.
