The main locations accessible within the world.
The Dome City is the host of many locations in Custom Robo Battle Revolution. A large majority of the game takes place within this structure. It is also houses a majority of the population and built as a safe point away from Rahu.
Background[]
In the aftermath of Rahu's rampage throughout the world humanity was left in shambles. With most of the world destroyed and lifeless, the survivors sought out a new home. Eventually the remnants of humanity discovered an area with minimal damage and developed a construct large enough for all of the worlds remaining population. Taking refuge within this new structure, society began attempting to rebuild what they had lost. However despite humanity successfully building itself up, there were those who feared the memory of Rahu and ruined world would never allow humanity to know true peace as before. To address this the Government developed a way to ensure that citizens would never have to deal with the traumatic stress of these events, creating the Memory Erasure Device (MED). With this in effect the government decided that the best way to ensure the world remains stable was to rewrite the memory of the citizens. With the MED in effect the memories of humanity's survivors were written to believe two truths: the world was entirely within the dome, and nothing had ever existed beyond that. As time went on these beliefs were instilled in youth as part of their education, and knowledge of the lost world became a secret known only to a select few.
The Dome also served a secondary purpose, a defense against Rahu's possible return. To further this goal a secret license grade was developed consisting of a small number of highly skilled commanders, The S Class. In addition to combating the Autonomous Robo, they were also tasked with keeping knowledge of the Outside World a secret from the general public.
