The Hero of Men is the name associated with a great hero spoken of in the legends of the Picori Blade and the mythical Light Force in the land of Hyrule during the Force Era told in the Minish Cap. He was the first owner of those two special gifts given to him by the Minish to assist him in his efforts to battle the many evil creatures plaguing the land of Hyrule long in its past.
"Long ago, during the early development of Hyrule, the kingdom was at peace after an age of chaos. One day however, the land was suddenly overwhelmed by evil creatures that descended upon it in swarms, driving the world into shadows and bringing the kingdom to near-ruin. As Hyrule neared the brink of collapse, the tiny Minish appeared from the sky and gave the Hero of Men the Picori Blade and the magical Light Force. Using these two special gifts, the hero drove the beasts back and restored light to the land of Hyrule.
To ensure the beasts could not bring further destruction to the land, the Hero of Men sealed them all within the Bound Chest. Sealing the chest with the Picori Blade itself, the Hero of Men was able to bring the destructive war to an end and brought peace to the kingdom. Meanwhile, the Light Force was secretly sealed within the body of Hyrule's princess to prevent its misuse, giving she and her successors many magical powers that would continue across the generations."
The Hero of Men is noted for very specifically not wearing the iconic hat. He also, at least according to the stain glass windows in Minish Cap, had notably longer hair than any of the previous incarnations of Link thus far. What if this game tells that story. It would make sense of the game talking place in Hyrule, if it actually does. Also, the sword he has in the trailer kind of looks like the handle of the Picori Blade. (No it doesn't. That's just a stretch)
