is the totally retarded name of the GoT prequil about The Long Night.
fun fact in exactly zero places in the entire GoT series is there a reference to 'bloodmoon'.
so it kinda confirms a lot of worst case suspicions that the show runners are going to continue to just pluck a few gems from the GoT lore and write their own trashtravaganza around it.
aka everything they did to ruin GoT.
