Fanfic Summary: What if it wasn't the virtues that got themselves corrupted, but an actual cookie corrupted them? Here we meet my OC Corruption Cookie, the one who started the Fall...
After the Ancients awakened and defeated the Beasts, Pure Vanilla Cookie suggested that they could try to redeem the Beasts because he still felt they only needed a friend. The other Ancients eventually agreed and thus the Beasts were on the path to redemption.
Later the kids were running around the castle playing tag when they came across an old door nearly buried in a corridor below the castle. It has the symbol of the virtues inscribed on it and, being the curious children they are, go get Pure Vanilla and Shadow Milk to help.
But what they find will change them all forever...
FYI - PureShadow, Kids call Pure Vanilla dad, Pure Vanilla calls Shadow Milk Bluebird, angst, fluff, beast siblings, blood=jam,
