Blood Song is part 4 of my Sabretooth series, Equilibrium: Of Cruelty and Pain. It is posted here on MET and on AO3. I still need to post it on AFF, but I will do so this coming week if I can’t get it done tonight. Blood Song will officially begin my (apparently new) ship of Sabretooth/Iron Man, which thanks to some naming help from CanuckleheadCowgirl, I shall dub “IronTooth”. Yay!
