Osario Altrane

Osario is Casimir's advisor on the matters of magical artifacts. 
This kind boy is exceptionnaly intelligent, educated and wise for someone around his age.
Unfortunately, he is way too humble for his own good and has low self-esteem. He was born into a family of talented mages, but having no magical abilities himself he thinks he is not good enough for them. Indeed, his father Master Altrane, the head of the Circle of Mages, looks down on him and finds his lack of magical abilities disgraceful.
