The Blasphemies were widely rumoured to be an artificial construct of some kind, a projection or Tinker-made creation.

↑As stated, they've attacked political figures. They're widely viewed as being in league to one nation or another, a superweapon being utilized to give said nation a leg up, but nobody's been able to work out who, exactly.
