I've started a new campaign based on Babylon 5. The player race is the Earth Alliance (with Omega class destroyers, Hyperion class cruisers, etc.) and there are five starting NPRs (Centauri, Narn, Dilgar, Drazi, Brakiri). I may add more. Obviously the Invaders are the Shadows.
I've decided to use the known system names as much as possible as they are used in that universe. However, there are a lot of minor systems with WISE, Gliese, etc. names, so I need to create some form of naming theme. I was thinking of having a few categories of minor systems and then combine each one with the Greek alphabet, so there is <theme1> Alpha, <theme1> Beta, etc.
What I am struggling to decide is the category and the names. One category could be brown dwarves for example, while another could be planetless systems. So I am open to suggestions about categories and category names that would work with the Babylon 5 theme.
