If you want to do a certain singularity memorial quest you have to complete the singularity. If you want to do Agartha memorial quest you have to complete Agartha. Since memorial quests tend to be the hardest bosses in the chapter(not necessarily the final boss, camelot's memorial quest is against gawain).
