In the lore of Diablo-3 you can see that the heroes have a specific background, with own lore and reason to enter this journey to kill evil, get revenge, etc.
- The female Demon Hunter.
The female Demon Hunter in Diablo III fled from her village as a child during a demonic invasion. She was the only survivor. After days, she was found by a Demon Hunter and was taken in as a member. Since every Demon Hunter has a story like this, it is possible that the background for the male character will be similar.
- The female Wizard.
This 19 year old female wizard was sent to the Zann Esu mage clan, but later handed over to the powerful Vizjerei since she was a "rude and uncooperative student," that the smaller mage clan could not control. They hoped the harsh discipline at Vizjerei "would break her anarchic spirit." Yet even the Vizjerei instructors were unable to rein her in. She was continually being caught seeking out dangerous and forbidden magics without care for herself or anyone around her.
- The male Monk.
The monk serves the Elder Monks of the monastery, who seek to destroy evil in all forms. He thinks of himself as the weapon of the gods against all that is evil. He is a peaceful, patient and good man who aids those who suffer, with no hatred against anyone, in contrast to the Barbarian. He is adept in Martial Arts, being able to defeat multiple foes without the aid of weapons.
- The male Barbarian.
This is actually the same individual from Diablo 2. He's aged twenty years, and he's got a personality in this game. Look at his gear; his [[armor]] has points on which he could impale himself. It's extra protection for the harsh environment, but it's also dangerous to him. The day to day life characters lead in this world is very hard.
- The male Witch Doctor.
The fearsome Witch Doctor of the umbaru is believed to be a legend by many, but Abd al-Hazir has seen them with his own eyes, documented in the thirteenth entry of his writings.
The second most sacred belief of the tribes is their philosophy of self-sacrifice and non-individuality, of suppressing one's self-interest for the good of the tribe. Their most current war created an intense social upheaval among the tribes due to an incident, of which details are lacking, but might be the reason the Witch Doctor has traveled west to Tristram.
But in no place (neither game or web) I found the real names of those amazing heroes. Did I miss some lore in-game where they talk about it? or you must be nameless to fight against the evil?
