A close examination shows that there's no essence battery involved, although by the same token, that means that the lattice was probably there to feed essence from the manse and hearthstone to the armor.<br/><br/>Constant flow of a very large amount of essence would equal a very hot, hot, hot armor.<br/><br/>And with some fiddling, Thunder finds out how to slide the plates around. The only problem is that it doesn't seem like it could be put on with the plates pre-shifted, and there's no way to get them to move while a person's wearing the armor. Or at least not one that doesn't seem like it would involve tools she doesn't have.
