I've noticed that some of the bosses in ICC don't have any lore behind them (or they might and I just haven't found it.) Fights like Saurfang, Blood Princes, Blood Queen, Sindragosa, and Lich King have some lore behind them. But other fights like Marrowgar, Putrcide, Fester, and Rotface. Does anyone know any lore behind those bosses or are they truly lore-less?
