I've been developing some backstory for the third. Third Mizukage was supposed to be the second one (back then there was a hereditary system for the position of Kage), but the Second Mizukage was eventually by the people, leading other villages to do the same for the later kage.

Third Mizukage was the one who forged all Seven of the Seven Ninja Swordsmen's weapons and was capable of using all of them (like Mangetsu). A few years after becoming the Mizukage, he decided to give out the weapons to seven of the most trustworthy and strongest kinjutsu specialists in the village and establish the "Seven Ninja Swordsmen of the Mist"
