The sigil transfers a bit of my own energy to the object that's enchanted. So, yes, it comes from me. Like a golem which is a soulless creation that can move and walk on its own. Typically they're made out of clay and mud, but-ah I do have a history of being unconventional. [ A smile. ]

Oh yes magic has rules they're a bit more...easily bended than science but it does have them.
