Tick is a level 52 elite named bronze drake that guards the Caverns of Time with Chronalis after you encounter Occulus, in eastern Tanaris. Due to the addition of the new expansion, Cataclysm, Tick and his companion, Chronalis are no longer a threat to players. They are currently friendly NPCs that fly around the Caverns of Time entrance. However, Occulus is now remodeled as an infinite dragonkin and has been dubbed: Occulus the Corrupted.
