Sliske

Sliske is a Mahjarrat loyal to Zaros who disappeared into hiding. As Azzanadra describes him, "Sliske the serpent-tongued, who delves the shadows"." Zemouregal calls him: "One of the more powerful of our number. Sliske has particularly strong shapeshifting capabilities and powers over shadows. I would love to catch this guy, but he's a slippery fellow."

Abilities
Not much is known of Sliske's powers. He is known for "delving the shadows," possibly due to his "powers over shadows," as Zemouregal mentioned in his notes. Sliske's "power over shadows" may also mean that he has great proficiency with the Ancient Magicks shadow spells, but also that he can access the Shadow Realm. Azzanadra has said of Sliske, "An ally he may be, but I did not become master of my Lord's legions without being sure of the powers wielded by those close to me. Sliske is one whose actions can be seen each and every day in the smallest of this world's details." He is the stranger in The Fall of Six who granted the Barrows brothers their abilities and is thought to have reanimated their spirits;the stranger in the tale is described as "delving into the shadows at its (the camp's) edge". Suggested by the fellow Mahjarrat's comments, it is possible that Sliske is intelligent and very cunning, as he was known to Azzanadra as "Sliske the snake-tongued" and a "slippery fellow" to Zemouregal. His "Snake-tongue" seems to be similar to the ring of charos "too many would assume this to be just his manner of speaking – he is far from being a snake. Rather, his words carry weight in the mind, and have a way of bending the weak to his will." as stated by Azzanadra in postbag 44. Also in postbag 44 Azzanadra Stated that:

"Sliske himself did not kill his Barrows toys, but it was the power he granted them that sealed their fate." This confirms that Sliske is connected to the Barrows brothers.

Current and future activities
According to Ashuelot Reis, Sliske (during the God wars) manipulated some saradominists to do his bidding (under the pretense of converting them as well as revealing how to wake Guthix from his slumber) in order to unleash Nex, a zarosian general, upon the world again. He was successful in doing so and Nex was free once more. Following this, Sliske disappeared.

Sliske's current whereabouts are unknown; however, a passage in a recent letter from the Chaos Elemental, known for hinting at future updates, seems to be referring to him: "That's where the shadows are shadowed, and even the delvers don't dare."

Further implying that Sliske is involved in future content, Mod Mark of the Runescape Content team said in a Q&A session that Sliske will not have his own quest, "but you may well call on his support in the near future." In a Q&A session on 11 February 2010 Paul Gower stated that Sliske would make an appearance in the Grand Master Mahjarrat quest, The Ritual of the Mahjarrat.
