Back when the Mist Alliance had been established, the moon elves of the Northlands had joined as well. Actually, since the entire Northlands had joined the Mist Alliance, the moon elves would have isolated themselves and become a weakling right beside the mouth of a dragon if they hadn't joined.
But even though they joined the Mist Alliance due to the circumstances, their status in the Mist Alliance had constantly been awkward.
How was the relationship between humans and elves? There was no need for me to go into any further detail about this sweet and sour relationship which could spawn countless stories.
