Artic - Chapter - 216 - The Emperor - Black Hand House
Soon, Artic had been informed of where is he was supposed to go. That's how he knew where the Black Hand was based on, which was the area where it was run.
The main location of the Black Hand, black hand island was on an island. It was called the Black Hand House, which was built on a large mountain on the island. The entire Black Hand organization depended on the administration on this island.
Although Black Hand House was built on a mountain inside the island, the entire island's resources and lands belonged to the Black Hand.
The size of the island was the same as artic's former habitat, earth. Of course, in the world where the mystics live, such an area could be described as the most "island".
Even from here alone, you could see what kind of power the Black Hand had. Going to the island has been a long journey. But it wasn't a big trip to Artic. My maxi would have given it to the island in a few hours.
