I can tell you now that there are some major inconsistencies with the official write-ups that will need to be addressed and that the lair part might be against the rules regarding personal wealth. It is never good to develop characters too early. You guys simply don’t know enough yet to be able to do it properly.

Nothing ventured, nothing gained. It's not like bits can not be removed, added or tweaked. However it is far easier to tweak something that is already made, than try to write up a bunch of stuff in a rush when you are Military Personnel - It's nice to be creative sometimes, even if its just for the sake of being creative!
Ulysses
Looking good - though is the "name" supposed to be ironic? He seems far too chatty to be nameless...
Tsunami
Its an avenue for the story, why does he record everything, why doesn't he have a name, why is he a mandalorian without a clan etc. My plan is for that to develop, he never new his parents and grew up fighting in the arena, his recordings are almost like he is documenting things he does in case he ever meets them.
