Soon after Dragonstar came out, I thought of an idea. What if the Dragonstar Empire invaded Toril. What would happen? Well, what happened was that I wrote a hypothetical Story Hour over on E.N. World entitled Realmsian Dragonstar.
While I only wrote one-and-a-half of three book story, it eventually spawned a play-by-post game on E.N. World, which is still ongoing. (We’ve had to take several breaks due to real life issues.) While the campaign began as a v.3.5 game, it now uses the Starfinder Roleplaying Game.
