The 'Female Custodes' or 'Femstodes' controversy erupted in April 2024 following the release of the 10th Edition Adeptus Custodes Codex, which featured a female character named Calladayce Tauro Magush. When fans questioned the change to what was previously established as an all-male brotherhood, Games Workshop’s official social media stated that female Custodians had 'always' been there, sparking a massive divide within the community. The meme typically centers on the tension between long-standing lore and modern retcons, often using satirical takes on the sudden narrative shift. It has since become a focal point for discussions on tabletop gaming culture, corporate messaging, and the evolving nature of the Warhammer universe.
