The Beast Rune has the ability to show and draw out raw power; passion, the violent emotions and spirits that dwell within all creatures. The official story states that High Priest Hikusaak gifted the Beast Rune to Mauro Blight in SY 236 to represent the right of the Blight family to rule the newly established Highland Kingdom. However the truth is that the Beast Rune moved to L'Renouille of its own accord and the truth was covered up and the rune's movement presented as a gift.
Although the rune functions as a symbol of Highland's power and was considered the nation's most important national treasure, it was never practical to attempt to use its power in anything more than a symbolic function.
During the Dunan Unification War, Highland Prince Luca Blight plotted the destruction of the world by releasing the Beast Rune, invading the City-State of Jowston and slaughtering the citizens of Muse City in order to awaken it. Many Golden Wolves appeared in Muse City as the Beast Rune manifested itself there.
After Luca Blight's death the rune was re-sealed in L'Renouille Palace and just before the end of the Dunan Unification War, Leon Silverberg released the Beast Rune with his own blood. The rune manifested itself as a two-headed Silver Wolf but the New State Army managed to defeat it.
Since the fall of Highland, the rune's whereabouts has been unknown.
