Factions
You can edit a faction by clicking on the edit button in the faction information panel. You can also create factions from the factions panel (both use the same form).
This page discusses the fields in the edit faction form.
General
The general tab lets you edit the basic details of a faction. You can also edit their goals and goal completion methods, and whether they operate secretly. These options help power events involving the faction.
People
This tab lets you edit the people who are members or leaders of the faction.
Meetings
This tab lets you edit the meetings that the faction has, with the option of changing when and where they occur.
