Dragonkin are, possibly, something like Dragonborn... except, you know, without any of the IP issues that might arise before the GSL is released.
It should be noted that many of these counters already exist in some form out there... Klaus was just awesome enough to put together this specific selection based on a campaign that the Fiery Dragon guys are going to be starting in the next week or so, when Fiery Todd is back from a work-related trip.  Just a happy, non-legally threatening, coincidence if anyone else can use them in their home games.
