The term "Lord Commander" typically refers to a high-ranking leader within a military or organizational structure. In various fictional contexts, such as A Song of Ice and Fire by George R.R. Martin, the Lord Commander is the head of the Night's Watch, a sworn brotherhood tasked with guarding the Wall and protecting the realm from threats beyond it. The role of the Lord Commander involves making critical decisions, leading the members of the organization, and maintaining order. This position often comes with significant responsibilities, including managing resources, training new recruits, and navigating political challenges within the broader narrative.
