Ogres are large, dull-witted humanoids seen in Cyrodiil. They have great physical strength, but are vulnerable to poisons. Ogres are associated with Malacath.
These are enormous Daedra with very little intellect, but which are chiefly sent into the mortal world to menace living things for the amusement of Daedra Princes. Ogrim are associated with Malacath. They are immune to normal weapons and can regenerate health.
Oxen are common beasts of burden on Tamriel. They are raised for their meat.
