I still use my own default vessel from my game the Saladin Class destroyer U.S.S. Xenophon, but I assume most people just use/ create their own.
I am considering combining Be Not Afraid and the new adventure into one little dual adventure module titled The Danger of Peace. If it comes together as a printed version, it would be offered at NO PROFIT to me--and a one time opportunity to get physical copy. The PDF's would of course remain free downloads separately.
