If you performed all 3 assigned tasks for either Romag, Kelno, or Alremm, youll be led straight to the presence of the High Priest of the Greater Temple, Hedrack. The party will find itself at #12 in the Temple of Elemental Evil, Level 4. If you did all 3 quests for Belsornig, hell simply point you in the direction of the 4th level, along with an encouragement to clear it out violently.
In any event, Hedrack has a task for you. Something is causing a disturbance on the 3rd level of the Temple. His guards have been unable to resolve the problem. Its now up to you. Note that refusing him at this point is a very bad idea. Youll instantly get attacked from all sides by practically everybody that resides on the fourth level. Bugbears, Ogres, Ettins, Hill Giants, Wizards, Hedrack, you name it.
As it turns out, the cause of the disturbance is a Hill Giant named Scorpp. He can be found at #4 in the Temple of Elemental Evil, Level 3. He also keeps a pet Worg named Splot for company. Scorpp wont be difficult to kill, largely because he never takes his hands off his crossbow, thereby provoking attacks of opportunity.
Kill Scorpp, and then report your success to Hedrack. Youll be initiated into the Greater Temple. At this point, the game comes to a close. The consequences of your actions lead to the ultimate victory of the Temple of Elemental Evil, with you participating in their ranks. For more information on your ending movie, refer to the End Movies section.
Please note that if you recruit Scorpp into your party and come back to Hedrack, Hedrack will go hostile and initiate combat.
