David Owden the eldest of the Admiral’s children. David's Mother Ruth did not want David, unlike his younger brother and sister, in his father’s world hopping planets. Ruth saw that David’s younger siblings took to their father’s world better, while David took after her and had a mind that was more focused on logic and science.
While David contributed greatly to the great strides project Morpheus made, those strides and his arrogance were part of his undoing.
David was one of the scientists that sided with the emperor and against the Admiral in wanting to find a way to salvage the Dreadnought class of battleship. Had the Admiral stood his ground and destroyed the dreadnought class, then his wife and son along with 198 others would still be alive.
