The following rules do not attempt to cover all contingencies and eventualities, so it is helpful to understand the goals of the fanon prior to writing. The goal of Tranquility Lane is to expand upon the Fallout Universe without changing what has come before, or rendering it unrecognizable. Avoid straining credulity, Mary Sue/Marty Stu characters, supremely powerful factions, and enormous post-apocalyptic nations. Use high-tech artifacts sparingly, and do not overpower mutations.
