Guthix in the first god wars was working to keep know one on top of the battle. He left one of his magical balance runes which Zamorak got ahold of. Combined with Animated Chaos Runes There was a bad effect. A baby demon that took half of Zamoraks power no longer having him be with the High up ranks of gods. It has made an escape from the abyss and when killed burns some of Zamoraks old energy it took to revive. It is estimated to last about 9,000 more years with the power it took.

Whenever you kill it You can see Zamorak stealing some of its power back in the shadows.

If you bring a Catspeak amulet and use it on a visage when you enter its lare it will be nice to you since you now have a demonical-speak-C amulet(cat and demon speak amulet).
