Background I do not really use any VTT tools for running games, but folks running Traveller of various kinds often like having deckplans, at least for the ship owned or used by the PCs. While there is no shortage of deckplans out there, sometimes you just need a new, custom one. A fairly common source for making one’s own deckplans is the set of Starship Geomorphs created by Robert Pearce a few years ago.
