Having overheard various people of Thark refer to him as G.L.U. - (Great Lord of the Undead) - when he met them, he said "call me Eddie" Thus, the anagram was spelled correctly.
He is a Force of Nature - the Undead.
He likes being worshiped as a God, so he does that too. Generally, not a nice guy. Always hungry
has a number of P.R. (public relations) guys who are working on his 'image'.
