Seven Island (Japanese: ７のしまIsland 7) is the seventh and most southern of the Sevii Islands towns, and the farthest from any major cities. At night, residents say, they can see more stars than could ever be possible in regions like Kanto and Johto, where light pollution from the major cities there causes all but the brightest to be invisible.
Seven Island is located on Seven Island, and as such is surrounded by the rocky terrain of the island. However, the population has adapted to this, and do not have a problem with Sevault Canyon's landscape in the slightest. The island has been left virtually untouched in its natural state and can be difficult to hike around because of this.
Although north of the town, Trainer Tower is a more prominent feature of the island, and many citizens think of it as a feature of their town. Trainer Tower is similar to the Battle Tower, that has various modes of battling, offering different rewards if they are beaten. Rewards are time-based: the lower the time taken, the better the prizes. It has sliding mazes and utilizes the multi-Trainer Double Battle feature introduced in Emerald as well. Unlike normal Battle Towers, items, such as Revives and Potions, are permitted to be used both during and between battles.
