Hot damn. From what I'm seeing so far, this is probably the most wonderfully executed system I've ever seen. This has a hell of a lot of potential. If you like, I'd be more than happy to help write up lore for all your ships, edit grammatical mistakes, and help flesh out the place in general.
Thanks Callahan! But I'd like to write up the lore myself. It is part of what makes doing this campaign enjoyable. However, don't hesitate to point out any grammar mistakes. Oh, and since you like writing so much, I'd love to see a story set in the Iota system.
Something I've noticed is that the ships don't really have a backstory. All you've got, it seems is 'this is a chunk of an onslaught, turned into a warship.' Or 'this is a (ship) that got modified due to being used in x role.'
Where instead you could have something (in regards to the onslaught pieces), along the lines of the enemies of the Hegemony being forced to break up and re-use pieces of the warships they kill in order to keep up the fight, and sustain combat losses (would be great to see the Iota PDF in a bitter struggle to maintain their system's independence, using such strategies, along with experienced frigates and such, and a few operational cruisers, but mostly relying on a jury-rigged fleet because of the drawn-out war of attrition).
Once the Iota system is really fleshed out, I might do an actual short story based in it. Instead of the 'short story' that is Independence. Which is basically just a serial novel.
