Interdimensional, a starship trilogy

The announcement of surface leave had come like a breath of fresh air. Bringing forth a renewed burst of excitement among the crew, and also stoking a mixture of relief and anxiety in captain Maguire. 


The latter sentiment was a direct result of the invitation to attend a high school reunion. 


As he had sat looking out at the superstructure sprawling across a vast area of space from a portal on the shuttle craft, he could not help but be impressed. 


The shuttle craft taking him and the bridge crew swung over the central core of the starship, on a direct course for Earth. 


Captain Maguire took one last appreciative look at the majesty view. There was more than a fit of engineering, it was pure poetry, a delicate combination of functionality and aesthetic beauty.
