Station on the Borderworlds
Characters will mostly be built using the standard Starfinder rules. Anything that is Paizo official rules is allowed.
StarJammer character options are also freely allowed, and the adventure includes rules from that line of products.
Other 3PP rules will be considered so long as the GM is able to access them, either through his own copies or online. Regardless of access, GM approval is required to ensure the concept will function in the scope of the adventure.
In addition to using the standard Starfinder rules, each character must select one of the special Campaign Traits. Each trait may only be selected once; no two characters can have the same trait.
Take note that characters will be about or just over 4th level going into the end. The module uses the "Advanced" experience track.
