Мафия 89. Nemesis

I think the factory number is actually the registration date on the forum, which is absurd, but here's the thing: 5 4 3_1 is the registration date on the Nefeli forum: 05/31/2012. 3_1 equals the 31st, 5 equals the 5th month, and 4 equals 2012, because the era of the 4th sun ends in 2012. So, something like that.
