Friend, what do you think of this theory of mine? In the abandoned cabin in the Wyvern mountains near Witetower there are 2 vengeful specters I don't know but I suspect that those enemies in that cabin probably had been his parents or guardians in life of our character, very possibly they were woodcutters and I think some strong and lethal bandits attacked and killed
and they took her little sister who would later be saved by a magician Turamio taking her to the capital of Thuram while our character being a child managed to flee miraculously and with difficulty
He would have to fight to survive in a hostile fantasy world so that a few years later, being an adventurer, he received a letter that motivated him to become a legend.
