Arcadia Movement building
The Arcadia Movement building was the headquarters of the Arcadia Movement and the residence for many of its members.
Sayer brought Toby Tredwell here to test his psychic abilities. Toby was subjected to electro shocks. Sayer ordered that the intensity of the shocks be increased, knowing they may kill Toby. If Toby's powers weren't strong enough to protect him, then Sayer had no interest in him, so he didn't care if the shocks killed him. The event did kill Toby, although the blame was put on Akiza Izinski. Sector Security performed a search of the building, but found nothing. Since Sayer had information that Rex Goodwin didn't want people to know, the investigation was halted.
Blister, Tenzen Yanagi, Leo and Luna visited the building for a meeting with Sayer, hoping he could help give them information on the Dark Signers. However, Sayer locked them-up. He stated Luna could speak to Duel Spirits, and tried testing Leo to see if he possessed anything similar by dueling him.
Carly Carmine infiltrated the building, disguised as a cleaner, hoping to find information on the Crimson Dragon, the Signers and the Dark Signers. She found a secret room in Sayer's office, but was confronted by Sayer and challenged to a Duel. Carly lost the Duel and the power of Sayer's attacks, knocked her out the window and to her death.
Carly was revived as a Dark Signer and returned to face Sayer in a rematch. At the same time, the Dark Signer, Misty Tredwell, who was Toby's sister also entered the building to face Akiza in a Duel for revenge. When Carly and Misty Summoned their "Earthbound Immortals", the area surrounding the building was destroyed by their geoglyphs. The building suffered some damage, which allowed Tanner and Yanagi to break free from their cell and collect the twins. When Carly used "Earthbound Immortal Aslla piscu's" effect to damage Sayer, Sayer was thrown down the center of the building from the impact. The attack caused further damage to the building, and caused Misty and Akiza to postpone their Duel. The remaining survivors evacuated.
The next day, Angela Raines reported on the incident and pointed out the building was the only thing left standing within the geogylphs.
In Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia, the player was a member of the movement during beginning of the game. It was later destroyed after the awakening of the Earthbound Immortals.
