You know, that makes me wonder... _why_ is dragon's blood 
infinitely more powerful that a human's?  It's a tradition, sure, but I 
don't buy it.  I see no reason why human blood, in a fantasy sense, 
should be as powerful, if not more so, than some overgrown flying lizard's.

I believe it is because asian dragons are thought to be creatures of 
incredible wisdom and power.  Wisdom and power that exceeds all human 
levels, including Cologne's.

        Wisdom and power far exceeding anything measurable by humans.  The
knight in shining armor vs the western dragon (in fairy tales) is an even
match, but put the same knight in shining armor vs an asian dragon and you
can be 50000% sure that the "Lung" will make mince meat of the puny human.

        Then D&D came out with a revised version of dragons, and I tend to
think of dragons as being extremely powerful, highly intelligent and steeped
in the mystic arts - their power is, IMO, one step below the gods
themselves.  That is another reason, among many, why I like kapster's Hearts
of Ice series.  Anyways, sorry for the spam.
