Zayd

They say six children were born with a rune on their hand. In Shal'Zaar, among the dunes, the hunter tribes prepare their hunts. To defend the children and non-combatants, the most gifted teenagers are trained day and night. Among them is Zayd, a warrior whose strength defies the laws of physics. The young man can multiply his muscular density. However, he burns huge amounts of energy and needs to eat a lot — so he's responsible for his own meals. Once he finally reached adulthood, an important figure of the desert came to take him in as a disciple.
