I spent another few moments surveying the advancing formation—an unstoppable wedge. So much of their magic rode in that wave that spells shattered, bullets bounced from unprotected flanks, bunkers crumbled. Barbed wire tore like it was twine. The snow all around them never seemed to melt before their advance, but it didn’t slow them down either. These ponies were so empowered by the land that none of its natural hazards could stop them.
