Richard nodded in relief, the days he spent in the city he used to marvel at its beauty and the arrangement of the buildings that looked like an artistic painting, so Caesar told him the secret of the city that only a few knew... The city itself is an integrated Array.
So Richard was not very surprised by the mayor's answer. The Imperial Capital is the strongest fortress in the four planets without a doubt. It would be strange if it fell so quickly.
According to Caesar's interpretation, his father Ruben personally designed arrays to protect the city's walls and atmosphere, and Jabba put his magic touch by drawing these arrays using the city's quarters and towers instead of drawing them underneath them, thus creating a three-dimensional array. It can be said that it is a joint work between the Master and his Disciple to ultimately produce the largest and most powerful array known to date.
