Layout and Locations
The Drum Rockies are the namesake of Drum Island thanks to their drum-like format. Because of their steepness, climbing the mountain is extremely difficult, but not impossible for people with superhuman endurance or animals adapted to vertical climbing. Lapahns are known to live in the hills at the base of the Drum Rockies, where they might start avalanches if provoked.
The Drum Castle is where the royalty of Drum Island once lived, being located at the summit of Drum Rock. After Wapol departed his kingdom to escape the Blackbeard Pirates, Kureha took the place over for herself, turning it into her new home.
The Drum Ropeway is the main method of travel between the tallest point of Drum Rock and the rest of the kingdom. It's a tram-way system that uses a trolley to transport passengers up or down the mountain.
Hiriluk used to live in a small man-made cave located on the lower mountainside of one of the Drum Rockies, accessible through a ladder. He also used this place as a workstation for his medical experiments.
