El Ingenioso Hidalgo Don Quijote de Las Irrana, Monsters' Hunter

A tragic story: He was a retired Hidalgo, a veteran of hundred battles. During the marriage of his only surviving son, the castle was attacked by a giant. The improvised attack ended with the death of the son and many peasants. So he took an oath: Hunt every giant and other monster in all Estalia.

Now he's part of a dwarf slayers company in the Irrana Mountains. His oath and his actions have the respect of the dwarves. This is an important sign how Don Quijote is renowned.
