r/StarTrekFanFiction

So am working on Fan Fiction on XCV 330 Enterprise the reason is that we don't have Abu stores on that vessel only the NX-01 and beyond. We know its a warp 1.8 Warp vessel I am currently working on the Story main cast. My main problem is the missions. I been thinking about having the mission been looking for Earths first Explorer S.S. Valiant. I don't want to make space Oprah but science fiction Should Starfleet first Explorer XVC Enterprise be a rescue mission or should it be about something else?
