My favourite headcanon in all of Elden Ring is the Lord's Talisman and the number Placidusax's heads; four on the talisman, but Placi has five necks with only two remaining heads; two died fighting Bayle, but where's the fifth and why isn't it on the talisman...?

Well, that's because his fifth head was the god the other four were lord to, like Marika and Radegon they inhabited the same body, think about the golden fire he breathes too, same as the Elden Beast & they're the only two(three) that do it.
