The Five Shadow Guards
Karsha, oblivious to the machinations against him, continued to advance steadily toward the white house where he intended to ask Ayarr's mom some questions about the island. So far, he has discovered some secrets about the island.
Initially, he thought there was only one island. However, after winning the map, he discovered there was an inner area with a hidden gateway somewhere on the island.
Then there was the discovery of another gateway leading to a place called Alcatraz, where a race of monsters known as Fallen Leviathans lived.
There was also the Abyssal Leviathan Snake, the strongest of all the overlords. However, the map didn't specify what kind of monsters they were, so he planned to gather as much information as he could before starting his missions.
Aside from his mission to kill the ten overlords, he had a few other tasks to complete first.
