Not the Slightest Bit

Ryu had Hrakka lay down, his mind still churning with several thoughts.

Theoretically, transferring Meridians was something that many were capable of. In addition, of all the Races in Existence, Demons were most definitely the most capable of this. 

This wasn't just because of some arbitrary connection between Demons, Summons, and Corpse Puppets, though that certainly played part of a role. 

It could be said that the Origin of Necromancy came from Summoning Necromancers. It was only after this that other paths of Necromancy disseminated into simpler, easier to manage forms.

This was all to say that all of the mutations and modifications that normal Necromancers were used to making, Summoning Necromancers had pioneered.
