Enter the gate and also be prepared to OSRS gold fight the level-200 Zogre King. Strike the Zogre King with protection from magic as he'll cast blood quake and a strange spell that drains your own stats. Widdle his health down to nothing and he'll change into a level-1 weakened Zogre. Cast the final spell and it will burn him but stays. Take them and come back to the queen. She'll reward you...
