What they saw was a spectacle that would even rival the Regalia. What loomed was a huge and metallic gray sphere, about the size of a small moon, with soaring antenna tower array mounted into the top central crown.

Many HEL-bomber ships were present outside the base in column boarding formations, seemingly preparing to board and use the concenter as their means of escape.

the adventure is only beginning....
