Where Frodo stands you can see a gray cloud. Admittedly the cloud is rather short, and has amazingly hairy feet but it is a very eldritch cloud. Occasionally a face appears within the anonymous gray, and you can see a familly resemblance to the statues found around this area. Frodo seems to radiate an aura of resigned sadness, rather than the utter evil one would expect from the undead. However he also reeks of magic, power and self assurance, you would be most unwise to cross him.
