Blood on his hands?

[mooseming]

Just encountered this while doing some research into alchemy.

cinnabar 

Cinnabar is the bright red ore of mercury sulfide. Known as "Dragon's 
Blood," the roasted rocks emit a thick reddish smoke, as pure 
glistening mercury oozes from cracks. Psychologically, cinnabar 
represents the hardened habits and terrestrial marriages of soul and 
spirit that must be broken asunder in Calcination to free the essences 
with which the alchemist intends to work.

Hum that pesky use for Dragon's Blood that Dumbledore discovered turns 
out to be the catalyst for creation of a HRX.

Guilty, guilty DD.
