The Decepticon Comm Tower was once situated in Ultrix. The seaside town and its seaport were taken over by the Decepticons at the start of the Third Cybertronian Civil War. The artists and performers who resided there either joined or faded away. The small tiered tower loomed out of place over what remained of the town itself, modular, brusque, efficient.
Inside the tiers are split with the control center at the second highest level, leaving the top for open viewing and entry-egress as well as access to the comm arrays. There was a simply designed master comm seat that the ranking officer used when on duty, complete with interface ports to the mainframe and comm array systems.
In 2021, the Decepticon Comm Tower was destroyed with the rest of Ultrix by a surprised orbital strike.
