And MoEP: DBs says they didn't. GWM gives yet another story. Each of the splats gives history from the point of view of that exalt/being. It is entirely unclear whether the Lunars had any effect, or simply tell themselves they do, so they can justify their conviction that the DBs are usurpers, and Creation would be better off if the Lunars put them 'back in their place' (i.e. as servants/slaves of the Lunars.)
