Jalod is a soldier under Lorena. He was an old soldier who had fought against orcs before anyone in Lordaeron knew of them and was rumored to have trained Admiral Proudmoore, which Lorena doubted. Jalod accompanied Lorena and her army out of Northwatch. They were attacked by orcish members of the Burning Blade clan. He was amongst uninjured soldiers.
It is unknown whether he survived the destruction of Northwatch and Theramore.
Since he fought orcs before anyone in Lordaeron knew of them, he presumably fought in the First War.
