Thanks for reading.
This is a universe I've been working on for a long time (well, a variant of that universe), with the AU Cardassia, and there are many stories already written for it--as well as the main Sigils and Unions
material, some of which is still related.
If you're interested, I can show you my theory on one way the larger political situation could work in a universe with the canon Cardassians. I have a story for that, too, and I can PM you with it. Needless to say, it's a very different outcome. Just let me know.
