Harrick thinks for a minute. "The other thing is this, These aren't the type of undead that would be out isolated by themselves. They are more likely minions of a greater undead. Also, since we have direct proof that of an evil worshiper of an Falan we are probably guaranteed that the Enternal are involved, or at least know about this." he rubs his belly. "Now, I don't know if they can identify us directly, but several shadows did escape. Those shadows can most likely identify Saren, but I'm really not sure"...
He thinks a little more. "It might be a good idea for the Falan worshipers to use those rings of non-detection and hide from both the constables and from the Eternals".
