No matter where your roleplay takes your characters, you only need post the RP in the area it initially began in. When moving from area to area you must be sure to realize that they aren't all accessible in the same way. Certain areas are connected right next to each other and are a mere walk away, some have train stations while others do not, and some are only accessible through another area (namely, Anmity Island is only available through Citrine Coast).
