Adumar's obsession with combat fighters turned their culture into one based upon duels. Whole minutes would go by before the gauntlet was thrown down and it was off to satisfy someone's bruised honour in daring deeds and death-dealing games of Old Republic Monopoly and planet-size risk. Considering Adumar has quite a few countries dividing its surface, you can imagine they'd be pretty good at this kind of strategy game, having had years to perfect their squabbling with internal politics. It was these nations that managed to somehow form an alliance when it came time to join the New Republic; one can only assume they'd found someone else to blame for any national strife, some unfortunate figurehead to lay it all on... *cough* Hobbie *cough*....

Surprisingly, despite Adumar's love of all things flight-based, they lost the ability to create ships capable of hyperspace travel (that's what happens when you get banished, you always lose something in the move). It was only after the New Republic's arrival that someone found these missing plans inside an old shoe box, mistook them for bills, and threw them in the nearest trash-compactor. Unfortunately, Adumar was a planet where the reckless youth died young (Old Republic Monopoly again). When New Republic pilots arrived in an effort to bring Adumar into the modern galaxy (not just for commodities, that would be wrong...) they soon found that this could not continue if the Adumari wanted to join the gang. The honour duels eventually faded, thanks to Red Flight pilots and Wedge being such a ladies' man.

Go figure.
