Finished!
Lily happily hands you the pieced-together ancient artifacts.
The mutation's aura is most concentrated in front of the Holy King's Tomb, right?
Go and open up these things there.
Also, although there is no proof that the nearby wind spirits
have been affected by the mutation, Lily hoped you might
eliminate them to prevent the mutation from spreading any further.
Be careful, and remember to come back and tell me if you stumble across any new information.
