Based on what Jack Kirby and Stan Lee wrote back in the day when Thoe was new to Marvel, yes it was Odin's power that enchanted the hammer and made it to what we thought we knew about Mjolnir. Aaron had destroyed that concept and threw it out the window. Now anything is possible, and continuity be dammed. This means twenty years from now a new PC writer will come along and makeup some crap about the hammer being made by Galactus' grandmother two universes ago. I stopped buying Thor when Marvel went all PC and they are going down a path I cannot follow or spend money on.
