The Trifecta Tower was a large office and residence building located on Trifecta Boulevard in the Mobian capital city of Landing. It was informally known as "White Whore".
It was the system headquarters of the Trifecta Corporation, the Solarian conglomerate that controlled much of the Mobius System's economy. In 1922 PD, it was hit by a terrorist attack, during which a cell of the Mobius Liberation Front took the senior operations officer hostage and killed numerous security guards and Presidential Guard intervention forces. After three days, the standoff ended with the death of the hostages and terrorists, and the destruction of large parts of the building. (SI3)
