Hastur Wiki (v.3.5 Dragonstar)
When I found this website I felt like I wanted to do back flips, I was so happy. Once I calmed down and went through the updated source material I realized that a lot more work would need to be done to update Dragonstar completely to the D&D v.3.5 rule set. However, the Hastur Wiki gives me a solid base to start with. Plus, there is some very good additional Dragonstar material on the page as well.
Another great website is Neo’s Datalink. Mark “Neo” Howe is a diehard Dragonstar fan and the owner and moderator of the Dragonstar D20 Yahoo Group. His fan-based work for Dragonstar is some of the best I’ve seen and has made my life way easier. His ship construction rules are a must read for any Dragonstar fan and his Book of Races has saved me from having to do conversions of the core Alternity races as well as giff and the core races from Star Frontiers.
Dragonstar D20 Yahoo! Group
After FFG cancelled Dragonstar, Dragonstar fans had to create their own communities. The best of the best is DSD20. This yahoo group is 770+ members strong and is the hub of Dragonstar activity on the Web. If you have a rule or campaign question, someone here can likely answer it. Therefore, it would be stupid of me not to seek out the council of my peers in the creation of Arcanum of the Stars. For while I already have a lot of material, the whole point of revisiting AtoS is to create more material for the Dragonstar campaign setting, as well as updating my campaign to the v.3.5 rule set.
Starfinder Roleplaying Game
I’m in the process of converting Dragonstar and Arcanum of the Stars to use the Starfinder RPG ruleset. The best online resource for this is the website known as Archives of Nethys: Starfinder RPG Database.
