A Journey into Other Dimensions
The Sentinel and the Controller.
The Sentinel and the Controller were invented by Nikola Tesla 1856 -
The Sentinel is a an armed (robotic) guard, developed by Nikola Tesla at the request of the Imperial Government and was introduced after the Government decided that policeforces across the country needed more resources to combat crime and to monitor the borders.
The Sentinel floats on a force field created by the Anti-Gravity field generator that was invented by Tesla a couple of years before.
The Sentinel is always interacts with the Controller, the Controller is static and can controle more than one Sentinel.
The Sentinel can perform indepently and autonomously.
Energy is passed wirelessly to the antenna on top of the machine
The glass ball allows the Sentinel to also monitor the adjacent dimensions and parallel worlds and to intervene if necessary.
The sometimes irratic movements of the Sentinel indicate that it is
taking action in another world or dimension.
The Sentinel is equiped with the Tesla Death Ray, which the inventor perfected by 1924.
After that time the Sentinel and Controller perform to full satisfaction and no big modifications were necessary to keep them up-to-date.
