About the power balance thing, is everybody sure that Mard is stronger than Silver? Well, he most probably is, but I'm still not sure.

And is the Dark King Keith mentions Mard Geer or E.N.D.? Most probably Mard because Deliora has been accepted into Tartaros in the last 7 years, but we don't know how long E.N.D. has been dormant for (or did I miss something?). Still, we know that his power was acknowledged by the Dark King, it might be because Deliora killed his predecessor or, maybe, because he proved capable of holding his own against Mard himself, that's what it sounds like to me. I'd love it if Silver was stronger or at least equal to Mard, but most probably not happening. :c
