Where does Assassin's Creed Chronicles: Russia fit?

So... these games don't have present time parts but still happen much later (and this one is the last one but we play it now). We will not bother about that for now. I highly recommend you to complete the optional 3 hidden Assassin logos (in the 3 Chronicles games) to unlock a secret ending cinematic in this game but we will come back to it much later.
