Thinking about writing spaceship combat rules for Myriad Song
Iron Claw doesn't seem to have any ship combat rules, but Rondo jaunts seem to be fairly rare, and probably take a second to get going

Would need to know how Elvers interact

Space needs to be a setting in this game, even though so much of it is about the Myriad Worlds, the Elvers being able to live in space makes space feel really important
If you've not read anything about Myriad Song, that will seem like babble, but it's a really cool RPG, basically designed for playing New Wave scifi with a focus on inhuman aliens and faction conflict

I love the dice mechanics, and the XP system being based around goals is fun
