Zuoken Zu-o-ken was the first non-dragon to complete ascension, he was once a human monk who walked the world helping those who couldn't help themselves. His time in a monastery taught him that balance kept the world safe, and that neither good or evil could ever banish the other from the world. With this mind-set he never set out to conquer evil, just keep those the innocent safe from it and keep balance. After two hundred years travelling he returned to his monastery home and sat in meditation for exactly one year, when he woke from his deep contemplation he had discovered a way to keep balance in the world, but first he needed to lay foundations for others to take up his place on Terrainia.

So over the next ten years he founded four Monasteries of Balance, one in each of the most prominent human settlements, then once more returned home and entered meditation This time he was accompanied by four fellow monks, each charged to lead a monastery once he was gone, and these four monks were the only witnesses to a miracle. By this time Zuoken had finally showed signs of old age, and with his task now complete he gathered his monks and laid down. Just moments after he passed away, his ethereal form rose from his mortal body leaving the monks were in both awe and serenity, he passed on their new instructions and passed to Zion, the neutral plane.

The Zenith, or Monks of Zen, are the only followers of Zuoken, the head of each monastery is part of an inner circle known as The Four, these four co-ordinate the monasteries work and live to be well over two hundred years old, each choosing a successor from their own monastery. Unlike their founder, none of the monks have reached the point of ascension, but they join Zuoken on the Astral plane nonetheless, where they stand beside him as equals, albeit without his divine power.
