But before you go there you should find and progress Save Seline Quest and finish Clash of Corporates Quest (asking Nikolaos/ Holoryx depends of your route or character you choose in the latter quest.) Nikolaos or Holoryx will offer you to become, a slave/partner/ or refuse altogether to join in TSB.
There is also a route of which King Slurg will invite you to TSB, him asking question if you are applicable to enter or not. (depends on how you made your conversation with that nasty VIP (King Slurg).
