The Marching Grounds is a dedicated "drill field" within the Remnant city of Gulthurub. It is a site of constant activity where the People attempt to master the ways of war taught to them by Magona. The area is used by leaders like Relzeb to enforce discipline and order, with the prose describing him "striding out into the field... flexed his arms" as he vowed to "straighten them out" when the troops struggled to master their "fucking formations".
This location highlights the Remnant's lack of natural military coordination and their reliance on brute force. Zel and his aides frequently express frustration here, noting that "the men just won’t stay in formation... no matter how hard we drill it into them". Despite these struggles, the Marching Grounds remains a central location for the People’s efforts to improve their combat effectiveness, serving as the training area for the Gatling gunners and soldiers who would eventually participate in the incursion into Sylrantheas.
