A settlement shaped like a Constitution-class starship, built by a people who founded their whole culture on stories told by a stranded Enterprise crewman a century earlier.
New Enda-Prize is the home of the Enderprizians in the Prodigy episode All the World's a Stage. About a hundred years before, a Starfleet officer they remember as En Son crashed on their planet in the shuttle Galileo and told them of his ship before he died. They have copied its uniforms, ranks and adventures ever since, handing the tales down as plays.
The Protostar's young crew answer a distress signal and are greeted by locals named James'T and Sool'U. Dal is delighted at first to be taken for a real captain. The away team learns that a sickness spreading from a cave called the Gallows is caused by plasma leaking from the wrecked shuttle.
The crew cure the illness and remove the source. When they are trapped, the Enderprizians fly the Protostar to the rescue, using the routines they have rehearsed all their lives.
