The leader of Team Darkness. Don't expect a warm welcome if you come in here uninvited. And even if you do don't expect the most joyous of greetings. Enter with a purpose.

Team Darkness's own PokeCenter. Here you can find their self-operated machines that heal your Pokemon and a PC that you can complete various transactions with.

The North Wing of the base. It's current supervisor is [Open]. This wing is where the air conditioning seems to be constantly on, making it absolutely freezing cold. You won't find anything but rooms here as well as the skylight to the roof.
Current Occupants : Razz, Fawn, Lyle.

This is the East Wing, run by [Open]. You'll find room here as well as the cafeteria for Team Darkness. Towards the end there also seems to be a newly built library section.
Current Occupants : William, Fran, Kurai.

The west section, run by [Open]. Here is most likely the most comfortable wing with good rooms, snack machines, and a rather large lounge for simple relaxation.
Current Occupants : Ciel, Enpowera, Annalee.

The battle arena where Team Darkness members test Pokemon's strength to see if they're fit enough to be usable. Some average members also seem to enjoy coming here and having battles with fellow members to pass the time.
