Arthur couldn't explain everything that happened inside the mysterious realm he went to, but one thing he could, and that was the fact he would now become the Elven ruler.
The devotees were more familiarized with the elves, and Arthur, being the ruler, meant more people would join their faith, which meant it was a good thing for everyone.
Speaking of faith, Arthur gained more free attributes after reuniting with his devotees. He guessed that these were all the attributes from the three months he was away.
After all of them talked for some time, everyone returned to their daily chores. Now, all the tribe members were practicing magic as well, even the ones that did not have the talent for it before meeting Arthur.
That fact intrigued him, and after asking Mohe about it, as well as talking with the others, he concluded that his blessing gave them aptitude for magic, and the constant blessings were actually improving it, as well as other aspects.
