Crimson Talon designated a specific Imperial Walker. This walker was produced by the Sith Empire after its reformation. It participated in the Empress Darth Acina's forces during the events on Iokath around 3630 BBY.
The Crimson Talon makes an appearance in Star Wars: The Old Republic: Knights of the Eternal Throne within the context of the War on Iokath. Specifically, should the player opt to align with the Empire, a decision that doesn't lean towards either the Light or Dark Side, the walker undergoes enhancements using Iokath technology. Subsequently, the player assumes control of this upgraded walker to spearhead the assault targeting the Republic base.
