Sharathteerk

Sharathteerk is a gargoyle and second-in-command to the Mahjarrat warlord Zemouregal. Sharathteerk is one of very few gargoyles known to display advanced sentience, and his intelligence has made him a prominent soldier in Zemouregal's army.

He appears in the Defender of Varrock, Ritual of the Mahjarrat and Dimension of Disaster quests, and serves as a sub-boss in the latter. He also appears briefly in The World Wakes.

Zemouregals second attack on Varrock
Sharathteerk plays his first role in the Defender of Varrock quest, in which he can be seen holding council with Zemouregal several times. During these meetings he reveals to Zemouregal that his cousin, Lucien, is somehow gaining power at a rapid rate and that he should seek to form an alliance with him. Zemouregal does not like this idea, however, simply because he knows Lucien would wish to lead such an allegiance and he is not a follower.

During the attack on Varrock, Sharathteerk is seen one last time when the descendant of one of the founders of Varrock, Dimintheis, uses his shield to vanquish Zemouregal's forces. At this sight, the gargoyle and his master flee to the North.

Little is known of Sharathteerk, and until his role in the brief Battle of Varrock Castle, his existence was not common knowledge.

The 18th Mahjarrat Ritual of Rejuvenation
Sharathteerk was present at Zemouregal's fort in the North while the player infiltrated it to destroy the black stone to loosen Zemouregal's control over Arrav's heart during Ritual of the Mahjarrat, and he is seen speaking to Zemouregal whilst he is preparing for the Ritual.

During the 18th Ritual of Rejuvenation, Sharathteerk is put in charge of Zemouregal's forces of armoured zombies and Arrav against the Barrows brothers. After the zombies have been defeated and Arrav freed of Zemouregal's spell, the Brothers attack Sharathteerk. Following the death of Lucien at the hands of the Dragonkin, Sharathteerk flees the ritual site with Zemouregal.

New Varrock
He serves as a sub-boss in the final boss fight of the Curse of Arrav subquest of the Dimension of Disaster quest.
