Araj the Summoner lords over Andorhal from the ruined city's heart. We know that he was the former leader of Scholomance before claiming the city as his own. To finish the key, we will need his signet - called a scarab - mounted as the head of the key.
Make your way into the heart of Andorhal, and break his hold on the city now that he is drawn into the open. Once destroyed, seize his scarab from his fallen phylactery!
You've come this far <name> - only the destruction of the physical form of Araj the Summoner will provide us with the means to finish the key. Get Araj's scarab by whatever means necessary and bring it to me - I will fuse it on as the head of the key.
Completion
Yes, this is it! I... again, I'm absolutely amazed at the depths of your heroism. It simply boggles the mind the lengths you are willing to go to achieve victory over the forces of darkness.
Allow me now to play my small part in this. I've prepared a special solvent that should allow me to secure the scarab on as the head of the key, infusing it with the power to breach the locked door of Scholomance.
It is useful to complete the quest [60] Alas, Andorhal at the same time, as both require slaying the same mob, and both require a group (if done at the quest level).
Patch changes
Patch 1.7.0 (13-Sep-2005): The text for the Horde and Alliance versions of "Araj's Scarab" now reflect the changes done to the Araj encounter.
Patch 1.3.0 (07-Mar-2005): The Araj's Scarab quest should now properly reflect that it is an elite difficulty quest.
