The first King of Water was Rhöig Waier Reynard

“The first King of Water was Reynard.  He was a Fierce and vengeful King.  In the Beginning of the Kingdoms, He created the floating island that the Castle of the Water Kingdom is now on.  He used the Island to hide from the many retaliation attacks against him.  King Reynard Is well known for His attacks against the Fyre, and Sky Kingdoms that surrounded Him.  His most famous attack was when He sent a tsunami to the dark Half of the Sky Kingdom.  Even to this day the lands are barren, and a wasteland.  This attack began the war between the two Kingdoms.  Each Ruler has a different excuse, retaliating against the Kingdom’s retaliation attacks.

“It was one of these retaliation attacks that Killed King Reynard, and left the Kingdom to His Son.  His Son sent an attack to the Sky Kingdom for revenge against his Father’s Death.  The cycle continued to repeat through each generation, leading up to the Current Queen of Water.  She was the Niece of the King when He was killed, and one of four survivors in the battle that ended the War.  After the attack left the only heir to the original line barren and childless, the Capitol stepped in, and called for no more counter attacks against the Kingdoms themselves.”
