The three realms corresponded with the three Legendary levels.
The Little Skeleton and the Dark Dragon Hound simply flew towards the Fate State realm, which was the largest and hardest.
The Purple Python and the white-scaled Vast Sky Thunderous Dragon, on the other hand, went towards the Void State and the Ocean State realms respectively.
Their mental marks had been uploaded to those realms. There was no need to confirm their identities again when they touched the boundaries as they flew in.
The three realms were Star State devices of the federation set for the three levels. However, not even an Ocean State being could endure a Star State attack!
A lot of pets waiting at the square went and joined the battlefield besides the Little Skeleton and the Dark Dragon Hound.
Many people had made thorough plans.
It was better to enter with the best timing than to enter early, as it was harder to defend the flag than to take it!
