Stone Slabs of Awakening

There are seven stone slabs depicting the steps necessary to do in order to ascend to a higher plane of existence. Last three of them describe the journey through the Great Tide and how to safely navigate it and make it to the sacred land that hides at the end of the journey. That is the land of ascencion and purity and the main goal of many treasure hunters and religious people.
Markus Ora claims that two slabs are in his posession and through meditations and his divine visions he has been able to put together the text of the remaining ones. That is what he bases most of his predictions on and that is what drives his many followers forward. There is no doubt that he has some detailed knowledge about philosophy and magical currents that enables him to be fairly accurate in his guesses - but majority of academia, at least those who know about the Ocean of Light movement, firmly believe that it's just it - guesses. The existence of these ancient slabs has not been confirmed by a neutral party and Markus doesn't let anyone, even members of his inner circle, to see the ones that he has.
There might be some little truth to the speculations as old stone slabs with various religious scriptures were part of many ancient cultures that lived on the islands throghout the ages. Some remnants of these have been deciphered by historians and gave away some information about the cultures and believes that were important to people thousands of years ago. But there is no way to confirm or deny any of the speculations about the Great Tide and other theories Markus Ora is preaching about. Some skeptics say that things like these damage the reputation of serious historians.
