Yellow-Eye Three

 is an imp found at Arkemyr's Manor.

Background
The third of the Yellow-Eyes, the previous imps were killed for asking idiot questions and stealing baubles. Three wants to outsmart them by watching for kabooms.

Yellow-Eye Three protects the Translucent Crystal, a pretty crystal that the imp thought looked valuable enough to warrant protection.
