Theres a book in ebon hold that you can look at and i believe it list s all the DKs created up to yours (i guess so you can see what number DK you are on the realm). Also gives some random (maybe?) comment related to them. I gots "Needs more cowbell", thought that was really funny. I dont understand if this is purely random, or somethign (as mentioned) that tracks all DKs created up to yourself. I dont recall seein it in beta. Can anyone with a DK shed some light on this?
