I would suggest the Traveller Hero CD, theres a ton of material, that you can use with whatever flavor of star hero for that matter with a bit of fiddling
and if you have specific questions about Traveller Hero, Eodin and Tancred and I wrote most of it, so ask away. I dont know anything about Project Wyrmstar, also I dont get any money from TH sales
if you already own either 5E or 6E of some flavor you should be fine.
