Pearl Coast
The story of Caspian, Conan, and Wolfy started years ago.
A few decades ago, while on an adventure with their father, Caspian and Conan encountered an injured wolf who was about to die, in the Dark Forest.
Being naturally attracted to it due to their bloodline, they took care of the young pup for weeks before releasing it back to the wild.
This act of gratitude made the wolf and the two brothers friends. After that, occasionally, they would visit the wolf in the Dark Forest and play with it.
They even made a special whistle that the brothers can use to contact the wolf anytime they were in the Dark Forest.
Till this moment, it had been a decade since the two brothers had met the wolf.
Now, the wolf was fairly old. It was already an overlord, being a [Grade-3] Demon Beast with its own territory. It even had its own family.
