As the Teslamancers lived in it, Tesla Tower is filled with traps and complicated mechanisms that make invading it difficult. It is guarded by deadlyrobots on certain places, in case an outsider somehow manages to get to them.
Tesla Tower also has labs, theaters, a factory and a winter garden.
Testa Tower was probably based on Wardenclyffe Tower (aka Tesla Tower), a big tower built by Nikola Tesla in the state of New York, U.S. If finished, it would have been the ancestor of modern Wi-fi technology.
