Katrina's Scroll

In the past few nights, shockwaves of magic suddenly appeared from the  Barrow , followed by a burst of howling. I believe someone has constructed a magic circle in the area. Please investigate this for me.

Here, take  [Katrina's Scroll]  with you. If you see any strange patterns or markings, copy them and bring the sketches back to me.
