Rage Binders are the Stone Summit magicians binding the dark fury of the Iron Forgeman to power the Forge deep within Sorrow's Furnace. Without the Binders, the Forgeman's fury and energy would overflow, causing the Forgeman to self-destruct. Killing the Rage Binders (all three at the same time) and destroying the Iron Forgeman is the objective of the quest "The Forge Heart."
