Interdimensional, a starship trilogy

A ground vehicle similar to the one that had captain Maguire had boarded, shot into sight and stopped some meters from the Sandawana. A side door slid open and the familiar figure of captain Maguire emerged and walked towards the starship. He stopped next to one of its landing pods and looked up expectantly at the starship. 


The crew were watching him on the giant monitor's big screen. 


"Why is he standing there, looking up like that?", lieutenant Anesu sitting at the navigation console wondered aloud. 


"Maybe his communicator is not working?", suggested lieutenant Tanaka at communications looking at the instrument panel before him, "I am unable to pick it up even though he is just outside the Sandawana". 


"Com, perch me through to the Sandawana's external public address system", captain Lucinda ordered lieutenant Tanaka at communications. 


"Done", reported lieutenant Tanaka after manipulating the instruments on his console.
