Just a couple historical, geographic, and political things you should know about Russia as you are starting out as Persia.
Russian history went as historical until March 1917, when Kerensky made a separate peace with the Central Powers. Thus, there was no Bolshevik Revolution (indeed, Lenin is still alive and in the Duma! ), and is governed by a coalition between Kerensky's Socialist Revolutionary Party and the Mensheviks. Its economic policy is that heavy industry, mining, railroads, banking, and similar activities are State-owned, while agriculture, consumer industry, and wholesale/retail are privately owned.
Russia has had an alliance with Armenia since 1924, and there is a Volga-Don Canal near the industrial city of Volgograd, formerly Tsarytsin. It can handle ocean-going shipping, so a possible trade route for goods produced in Northern Persia would be up the Volga, through the canal, down the Don River to the Black Sea, and thence to Europe.
