Ogri

Ogri is the head butler of Killorn Keep.

Ogri was happy to talk with the Avatar in Ultima Underworld II. Ogri revealed that his family was in the castle's employ since it's creation. Ogri didn't know exactly what kept the castle in the air, but warned the Avatar that there were rooms in the basement that shouldn't be entered (with good reason).

Ogri also bemoaned the loss of the Killorn Banner to Praecor Loth and was real happy when the Avatar returned it to him from the Tomb of Praecor Loth. Following this, Ogri revealed that he did know about the two Brain Creatures that kept the castle afloat and told the Avatar about the secret door in the barracks.

Being in expert in ancient artifacts, he also taught the Avatar many things about lore. However, it became clear that his age started to have an impact, since Ogri obviously was in the first state of dementia.
