Mal (Cycle of Hatred)

Mal is a soldier under Lorena. He had served in Azeroth's navy years ago. He accompanied Lorena and her army out of Northwatch. They were attacked by orcish members of the Burning Blade clan and he got injured. He was then taken to Theramore, but it is unknown whether he survived or not.

Speculation
Him serving in Azeroth's navy may mean that he comes from the Kingdom of Stormwind as it was sometimes referred to as Azeroth.
