Sivana Tower is the main headquarters of Sivana Industries.
Sometime in the 2018 holiday season, Thaddeus Sivana arrived and interrupted a board meeting at the headquarters. After explaining to his father that the events he experienced when little were real and being threatened by his brother, Thad threw him out of the window and unleashed the Seven Deadly Enemies of Man. In the ensuing chaos, the monsters attacked and killed all the remaining board members. Thad then took over the company and let Greed kill his father.
