Zeta-Tube Hub
Titans Tower Zeta-Tube Hub is located in Subbasement Level 1 for safety reasons. Firstly, it makes getting to the Tubes harder and therefore lessens the threat of unfriendly forces making their way anywhere they shouldn't be and, secondly, it makes it harder for anyone to beam in and make an attack on the tower because they have to move upwards towards the important floors.
The Zeta-Tube Hub of Titans Tower has many different Tubes. Each Tube is assigned all the inward and outward travel to another Zeta Tube station.
