Just south of the road from Orcish Byway to the Nor Plat Border Wall, you will find a small cabin that resembles a torture chamber. Inside you will meet the Insane Scientist Kragik.
Catch a few Orcs for my unholy experiments.
Who are you? Ah an adventurer, very good. You can do something for me. I am transforming Orcs into undead minions and my need for fresh supplies is urgent. Soon my army will be large enough to control the whole world!
Get me a few Orcs.
This guy is definitely out of his mind and must be stopped, so talk to him again.
The scientist and his two thugs will attack you. Inside his cabin is a tight space, so you will not have much room to maneuver. You might want to make sure you are as close to the down as possible before talking to him. After defeating them, talk to the orc that is in the room.
You let the orc go and the quest is complete.
On the table next to the dissection table is a an Easter Egg: one of the "Vitruvian Orc" anatomy charts
