There have been sorcerer-engineers who have tried to make a second manse just as powerful as the Sword of Creation... but they can't. Â Only the Primordials can do it.What I love about that statement is the fact that Autobot found it. What the hell was it beforehand during the reign of the Primordials? That's my question.
I guess Autobot didn't realize that the core of Mount Meru was actually a braided column of all naturally-occuring magical materials, bound together, until he actually decided to poke his nose around the Isle he'd helped fucking create from nothingness.
