Your work is too good! I am now obsessed with Orion's Arm! Do you have any social media I can follow you on?
You may want to check out EmperorMyric and the Ancerious Galactic Galleries. While both are softer sci-fi compared to OA (by and large my favorite science fiction universe), EmperorMyric's universe seems to be on the path of becoming as diverse and interesting as Orion's Arm, especially the collaborative Ancerious Galactic project.
That is ManyardButler's specialty but there is a vampire character in eburacum45's gallery called Herrick Thane and I feel it would be cool if he conquers Planet Fratboy North Korea and transforms it into a dark but prosperous Space Transylvania.
