The revolutionary Pamphlet is a miscellaneous item obtained from a woman near the Kremlin in Moscow. The purpose of the pamphlet is unclear, though it may allow you to meet with the governor of Omsk the same day you arrive, without spending a night there. However, if caught still with the pamphlet in your possession when in Vladivostok, you will be arrested and put in jail for several days*.
*Arrest and jail time is almost unavoidable in Vladivostok. If someone can add detail on how long the jail time is, and if it's upon arrival in the city, that would clarify things.
