Agate Village is a serene sanctuary nestled in the heart of Orre, a stark contrast to the arid landscapes and criminal activity elsewhere. This peaceful village is home to the Relic Ring, a sacred site where the process of purifying Shadow Pokémon is deeply understood. Upon reaching Agate Village, you'll gain access to the Relic Rock, which plays a vital role in the purification of your snagged Shadow Pokémon.
Furthermore, Agate Village serves as the gateway to Mt. Battle, a colossal coliseum where trainers from all over Orre gather to test their mettle. Mt. Battle is a series of challenging floors, each culminating in a battle against a strong trainer. Progressing through Mt. Battle is essential for gaining experience, obtaining valuable items, and ultimately facing some of the most formidable opponents in the game. It's also a prime location for snagging rare Shadow Pokémon. Mastering Mt. Battle will significantly strengthen your team and prepare you for the later stages of the game.
