Bring the Imp in a Jar to the alchemy lab in the Scholomance. After the parchment is created, return the jar to Gorzeeki Wildeyes.
1x Parchment Created
There is one more process required for Mor'zul's parchment; I need paper infused with Xorothian stardust. And... I'm afraid I can't do that here. I don't have the equipment!
There is an alchemy lab, however, with everything needed. It's in the Scholomance, on the isle of Caer Darrow in the Plaguelands.
I can't make the trip, but here - take this jar. There's an imp inside who is quite clever. Let him out at the alchemy lab and he'll infuse the parchment.
