Also the librarian at the mages college is an older male orc.
He's clearly not really associated with the stronghold-style "True Orcs", and it's questionable if he is a mage or just a librarian who is very serious about his job.
However, many orcs are just sell-swords and have completely left their stronghold ways behind, so if you want to role-play, playing as one of those types makes just as much sense as any.
If there is any sort of higher virtue orcs would aspire to, however, it's "survival"... Having restoration magic to help yourself survive in the wild would not be seen as an act of weakness, and they'd probably pay battlemages a great deal of respect for balancing the way of the warrior with a few fireballs for good measure. Just make sure you can still throw a mean punch, and take a beating, too. Wearing all-orcish armor would be a plus.
