According to Hopespear, the Plain of Mud is an area just north of East Ardougne, where there was once a great battle fought between different tribes of goblins. It is so called because during the days the battle raged, it rained constantly, causing the ground to become very muddy. One night during the battle, Hopespear had a dream and Big High War God told him that the fighting must stop, and that one day, the Chosen Commander would come to lead the goblins to victory. He told the generals who stopped fighting, and decided to build a temple, which sank into the mud, so they made it a secret underground temple. The temple is now accessible via the Goblin Cave. Players can teleport to the area using a Plain of Mud Sphere.
