It seems that there are no active spells on Drelev. However, you notice some traces of a strange magical aura. It reminds you of the one that filled the chamber under the Old Sycamore where you fought Tartuccio. One could assume that these traces were left by some powerful artifact, but there's no guarantee of that.
