The Red Blade Unit, also known as the Red Blades, were one of the last fighting forces involved in the defence of Old Targonor during the Undead Invasion.
Under the command of Rastus Willem, the Red Blades engaged in delaying tactics, ensuring the safety of the civilians fleeing from the city.
It is believed the Red Blades perished to a man during the defence, and it is unknown if a unit of this name exists in present times.
Their last days are told in the lore serial Willem's Stand.
