World's Blessed: World Mage

The line between reality and illusion is blurry. What actually is real? Atlas after a desperate turn of events gets an ominous task from a tree.... Could this be the only way to find out the truth? As the one blessed by the World, it is his duty to protect it but is he willing to? and what is he supposed to protect it from. And where does his GM authority fit into all this? PS. The main character is only interested in men and while there may be romantic tension and possibly long term romance if it fits into the plot it's not the driving force of the book. Anyone uncomfortable with this please don't read.
