>>34089431It's just a place where you can rebattle some trial captains daily. Ilima, Lana and Mallow/Kiawe depending on the version. Sophocles is still a league challenger, Acerola is still an E4, and Mina for some reason can only be battled once.
You also battle Ryuki there (only once or twice, then he goes back to being a league challenger), and a few random trainers like those battle restaurants from XY.
