Well, half-ogre are tolerated in this world. If you read my other game, the village of Prumen, there is an NPC Half-Ogre living in a small village at the northern border of the country. He doesn't fit well with the villager, some are scared of him. He was the cook in a lumberjack camp and came to town once a weeks or so to buy food for the camp.
So I have no problem with such a character. I don't see your signature, but if I remember correctly half-ogre have a +1 lvl adjustment making him a 1st level wizard.
