You gain membership in a faction. You're regarded as a promising but untested agent, and you're allowed to operate independently. You can be assigned tasks to further your faction's goals, and you can expect rewards and promotion if you succeed. When engaged in a negotiation with any member of your faction, their patience increases by 2 (to a maximum of 5).
Additionally, the Director assigns you one of the following benefits, as appropriate to the faction in question. The Director can also create a custom benefit for a type of faction not noted here. You can use this benefit only in a settlement where your faction has a presence, and once you use this benefit, you can't use it again until you complete a task for your faction.
You can gain this title multiple times, once for each faction. You can be stripped of this title if you act against the faction's interests.
