gaians: the infocard states that they have partly given up their ideas about gaia and resorted to low level piracy.
about terrorists:
the terrorist ID states that only YOUR roleplay dictates your targets. including no necessity to ask for tax / cargo.
terrorism as a xeno is not the same. i don t think they are allowed to destroy a trader without asking for a tax. i think i remember a thread about this one feature of the xeno ID - and it was said that it does indeed say terrorist, but it is not identical to the terrorist ID. xenos are by the rules - pirates.
so, we do have only generic terrorists being real terrorists - every other faction i think is considered pirates and are not allowed to blow anything up without a faction based RP, and when its about traders without asking for a tax.
