Professor Carlos Julian Diaz, ending his employment at a young forty-one, was ready for a peaceful and leisurely retirement from college teaching. However, there was something he wanted to try - something that had been in his mind for a long time. In this day and age, new technology certainly brings people closer. But could he satisfy his dominating tendencies long-distance taking advantage of remote communication methods? Professor Diaz was ready to find out, and knew exactly where to find his first willing subject. Come, let yourself be captured by the imaginative world of The Professor.
Tez has been writing short gay erotic stories for over ten years, keeping his work mostly to himself. In the fall of 2009 he decided to test the waters and go public with his first book, "The Fortress and Other Stories", which compiles four of his best short stories. The Fortress was followed shortly after by his first work of yaoi style fantasy/fiction, The Clan of the Mancats, which was divided into two books due to its initial length and the will to continue the series. Before immersing again on the Mancat series, Tez published what he considers one of his best pieces: Task Master. Tez firmly believes in the joy that all art forms produce and supports international emerging talent. He has commissioned promising artists to portray his characters, and those pieces can be found on The Clan of the Mancats page on Facebook or on the Yaoi Gallery website, posted within his club aptly named "Homotheria". He decided to take the name of one of his main characters, Tez the Manguar, as his nom the plume. Tez's name came from prehispanic mythology: one of the aztec god Tezcatlipoca's forms was a jaguar. Spanish being his native language, Tez will definitely create Spanish versions of his books. A fan of Anime since childhood, Tez hopes that his Clan characters and their stories will one day become animated.
