Sliske (pronounced SLISS-kay) was a mysterious, cunning and powerful Mahjarrat responsible for the death of the god of balance, Guthix. Although he was always loyal to Zaros, events following the death of Guthix have caused fellow Zarosians to doubt this and his dubious actions eventually led to his excommunication from the Zarosian following. He was also the first Mahjarrat to switch allegiance and follow Zaros in the Second Age, after which he became the praefectus praetorio in Senntisten. Azzanadra describes him as "Sliske the serpent-tongued, who delves the shadows" and Zemouregal calls him: "one of the more powerful of our number" and "a slippery fellow."
