"Your objective in the Trial of Eternity is simple. For reasons, as of yet unknown, the Henali have detected signs that the barrier that keeps the Trial of Eternity inside a segregated zone of existence is beginning to unravel. These are very early signs, of even if it does end up happening, it will still be thousands of years in the future. But there is no need to wait until the problem has grown to treat it.
"You only have one mission in the Trial of Eternity, with another bonus objective that is not mandatory or even expected. Your mission is to identify the reasons behind the weakening of the barrier, and your bonus objective is to resolve the issue. The time frame for this mission is three years. If, within three years, you are unable to complete the mission it will be treated as a failure, and you will be sent to a subsequent portion of the tourney based on your performance.
