Gladly! The Repository's background is rather unclear as of yet, since there haven't been much development on it within the articles. We know there was a possible precursor to the Repository in medieval Europe judging from SAP-002, and from other miscellaneous lore pieces, we know they began in Germany, most likely having some sort of comeuppance during world war 2, which led to a rivalry or disdain at the very least, for Russia and communism in general, namely the Group of Intrigue "The Red Armiya".
And I must say, I'm extremely surprised to see that the SAP Repository wiki actually has fans, or one at least. Love to see more of you on here, whether as a member or just idle forum user.
