Ostrheinsburg Castle Throne Room is one of the stages featured in Soulcalibur IV, notably used by Raphael Sorel and Tira (although Raphael also uses the Ostrheinsburg Castle - Twilight stage in Arcade Mode, and Tira uses Wolfkrone Monument in Character Creation). Notable features include a chasm at one end of the room as well as a line of knights who serve as a wall. These knights actually move forward over the course of the battle, shrinking the stage area a bit. These knights are in all black, and half of them are wearing the Warthog equipment set, the other half being impossible to make in character creation. In the Tower of Lost Souls level "Blade Piercing Wall", you fight these knights. The stage returns in Soulcalibur: Broken Destiny, with the difference being the moving knights missing but in exchange, it gains another ledge near the lions for extra rings outs.
- This stage is the primary setting for the story endings of Xianghua, Amy, Raphael, Voldo, and Tira.
- In Soulcalibur IV's Arcade Mode, this stage is at times used for Sophitia.
