After closing the sacred grounds of hiel academy, Dan had begun to make some improvements to it. Like a furnace that needed the constant shoveling of coal to keep going, Daniel kept cultivating the Mindhive's artifact with his power, sacrificing bits and pieces of his planet which would recover with time, and improving its natural essence.
Daniel really had to thank his lucky star for finding an artifact with the power of the Door to the Dream State. Most other artifacts would have simply allowed him to gain an increase in battle prowess, but when combined with his own, no other artifact was as useful to him as that one was. An artifact that would allow him to recycle his own power, and turn it into ownerless true immortal essence which could be used to cultivate not only by him, but his friends and followers.
