Carved directly into the mountain caves surrounding Burole Town, the Burole Town Gym is dark and winding, and while you don't have to worry about wild pokémon encounters while walking along the path, three trainers will challenge you to test if you are "man enough" to face Davern. Back in at furthest depths of the cave you will find Davern, blocked by a strange door; you have to find a Bright Gem too open it.
