With regards to the seal-sealing especially, it was a major problem that showed how far they had to go. Because if you noticed, Anubesetesh, an Eternal with more than 75 points of Eternal Power had never had to seal himself, whether in reality or in the game!
The why was simple. He had full control of his power having been God-King of his race, fighting in many conflicts and mastering his extreme talent while forging new paths ahead. He had long reached the point of achieving full control of the blessing he had as a miniature protagonist himself, whilst even slowly prying the way open to new paths.
In fact, coming to Boundless and witnessing all this has caused the Tomegamon God-King to have new ideas and endless inspiration, which was why he was not often seen around easily.
