Slon the Rook initially appears alongside Kon the Knight. The two are summoned by Bishop Ladja to kill Pankraz in the Ancient Ruins and fail to do so, being unable to stand up against Pankraz's might. In response, Ladja holds The Hero at neckpoint, threatening to kill The Hero with his scythe and condemn his soul to eternity of damnation in Nadiria if Pankraz does not stand down. Pankraz complies, thus allowing Slon and Kon to throttle him until his HP runs out. Ladja delivers the killing blow, and the three take The Hero and Prince Harry to Crocodilopolis to be slaves while the Great sabrecub is left behind.

Slon does not reappear until many years later at Talon Tower, when The Hero is an adult. Slon is guarding the Dragon's left eye while Bishop Ladja is guarding the other eye, both being dispatched after Zenithia's partial restoration to prevent the party from fully restoring the flying castle to its original splendor. He does not seem to recognize The Hero, only knowing him as a threat to the Order of Zugzwang that must be snuffed out. Unlike most other major bosses, Slon's death is not visualized on-screen, with him simply disappearing after his defeat.

While Slon did not recognize The Hero, it is evident from the Party Chat immediately succeeding the battle that The Hero did recognize Slon, with his children remarking that The Hero seemed very perturbed.
