The Lunar Condemned Center is a gigantic building located on Rigel that acts as a prison for high class criminals judged too dangerous to remain on Aensland for the safety of others. It is well known for being unbreakable and hasn't met a single breakout in 250 years of existence due to both it's location and the security measures taken in order to keep the criminals under constant surveillance. Nonetheless, a rather troublesome sequence of events also takes place in this huge building during a scenario called the Viper's Nest and ends up on a catastrophic note.

Notable "criminal" residents:

- Soliman Prime

- Magissa

- Cipher Knight

- Derringer

- Gilgameth's remains

- Anti-Seiyu
