I've been creating posts that archive the actual rules of AD ASTRA, modified from my older STAR WARS REMIXED game to be... well, less Star Wars specifically, and more "generic" space opera maybe you could say, but really more specific to my AD ASTRA setting.
You saw a good four posts today, and they were all added to the AD ASTRA menu button at the top there, which will be a permanent feature. I've got at least 5-7 or so more posts before it's complete, depending on how I modify the Star Wars material (or chuck some of it, if it isn't relevant) and how I break it up.
If you just come here to read blog posts (as if!) you'll have to bear with me as I take another day or two to complete this project. Sorry!
In the meantime, here's a pretty decent image that suggests what I imagine my Knight's psionic weapons would look like. Imagine a shield of the same ethereal energy on the other arm, and you're good to go!
