The unnamed Baron of Vo Ebor was an elderly gentleman who wed Nerina, Mandorallen's love. Fortunately for Nerina and Mandorallen, the Baron of Vo Ebor succumbed to his grievous wounds suffered at the Battle of Thull Mardu during the time of Guardians of the West.
Upon the elderly Baron of Vo Ebor's death in 5377 or 5382 (Guardians of the West says it is the summer of Garion's 23rd year, although the Rivan Codex says this occurred in 5382), Sir Embrig, the nephew of the Baron of Vo Ebor, inherited all that the elderly Baron had, including Nerina. Sir Embrig, the new Baron of Vo Ebor, in his drunkenness, had promised the hand of the grieving Nerina to his drunken cohort. This insult resulted in the Baron Mandorallen of Vo Mandor coming to avenge this outrage, causing regrettable fatalities and other injuries and almost a civil war in Southern Arendia between Ebor and Mandor (and their friends and allies).
Belgarion King of Riva had to personally settle this dispute.
