Anybody have any ideas on rules for characters making a drift drive from scratch? I'm running a party who has wandered pretty far off my expected path, and ended up with a ship without a functional drift drive, basically cutting them off from the rest of the universe. Is this even something they can do, or would it require such specialized equipment that only big corporations and the like could even attempt it? So far, the only details I've been able to find about the construction of DD's is that they are tech only, no magic, but other than that, I cant find any details for how they work, are made of, etc. I know that shipyards can modify them, or replace them, but are they black boxes that only certain illuminati know how to construct, or what?
