I am also working hard on Sir Theodric's background. I want to keep it open enough for the GM to add in things if he wishes. Maybe he has forgotten some things - INT and WIS might not have been as low as they are now when he was alive.
So far I have he was born in 3793 and became a Knight of Ozem in 3814. He was present and saw the defeat of Arazni and thus rightfully fears The Whispering Tyrant.
Died in 3826 and missed the final battle for which he is slightly ashamed.
Lot of info out there just need to figure it all in.
