Idk i think it is actually, as Dragon said the real sh** starts when the holy knights are on the move which means the government is about to get serious, if they sent them to Elbaf then it means having Elbaf under their control is crucial for the WG.....
Could it be because of their military might ? I mean idk they already have at least an ancient weapon + the navy etc, so imho there's definetly something more lore related in elbaf worth focussing on Nika is just the glue that ties all the pieces together maybe the WG just want to take out those pieces since Nika is so slippery xD
