As threats of Blackrock Orcs grew, he sent agents to [[Blackrock Mountain]] to investigate. While traveling with the information they gathered, he was ambushed by a [[Dark Iron]] raiding party. Only one of his men, [[Ragged John]], escaped to tell the tale. Marshal Windsor was captured and imprisoned, his hammer taken by the Emperor, [[Dagran Thaurissan]], and the precious information seemed lost.
In [[World of Warcraft]], an [[Alliance]] [[player character]] can discover his notes, scattered among major individuals of [[Shadowforge]] City. Returning his notes restores Windsor's hopes, and the player escorts him to freedom. Returning to Stormwind, Windsor is greeted as a hero, despite orders from [[
Onyxia|Lady Katrana Prestor]] for his arrest. Windsor proceeds to Stormwind Keep to reveal Katrana's true identity as Lady Onyxia before being slain by her.
