The infant vaccination mentioned in Dunkelzahn's Will, was made based on compounds and enzymes found in dragon blood. Those who developed the vaccination believed they were imparting increased longevity to their children, while others (like Lofwyr) believed Dunkelzahn was attempting to create a new draconic servitor race. According to one of the leading researchers, the vaccine may have resulted in a new metatype, and the date was critical (during the arrival of Halley's Comet), as the mana level had to be high enough for the vaccine to activate. The vaccine was destroyed before it could be distributed by a raid of Humanis Policlubbers, who were indirect pawns of Lofwyr.
