After the Gold Rush Character Creation
From AAFNRPWiki
Origin Path
When using the Origin Path chart to create your characters, feel free to select them as you wish as opposed to following the rules as written. This will allow you to further customize your characters as befits people as familiar with the setting as you all are.
Generating Characteristics
Players are encouraged to use the optional rules for generating characteristics as described on p. 14 of Rogue Trader. These rules are as follows: Each characteristic starts at 25 and the players have 100 points to allocate as they see fit among them. The only restriction is that no more than 20 points can be allocated to any one characteristic.
