I have now enjoyed 12 hours, sweeping the monastry and Arnika, I think I got it all, got it all, got Myles and Vi in my party rubbed the bank and the vaults,found Marten's ID tag in the jail, chatted with the hologram and found a mikro chip in space port, also got the the wheel key and use it, but thats about it, do I miss something? I got a nagging feeling, that there is something I overlooked!

You'll need to come back to Arnika for a few things, but that won't be for a while.
Talk to Antone about custom armor and weapons so you can get started on those, then head out.
