Ogres are not necessarily evil creatures, but do tend to treat smaller creatures as a potential food source. Most standing above seven feet tall and powerfully built they make strong and powerful fighters. The fact that all Ogres are quite dumb and gullible make them sought after as mercenaries, but may also work as bouncers or bodyguards. Ogres are careless, clumsy, noisy, love wrestling and using their large fists will knock-out most opponents.
Some Ogres have spell-like abilities, they don't have any natural ability to cast spells as a sorcerer or mage, so its spellcasting ability usually isn't very strong. Commonly known as an Ogre Mage they are still fundamentally fighting creatures, despite their magical abilities.
