Obsidian Lab

Located in a cave set in the cliffe face, this hidden lab is where members of Team Obsidian can recieve their starters, and are hacked onto the trainer list. However from time to time someone who has heard a rumour about the team, manages to find their way to this hideout and will join the team at the same time as recieving their pokemon.
The pokemon recruits get tend to be whatever they have free at the time, and it is basically down to luck.
