Okay the titans don't oversee the slaughterhouse, they just oversee the pasture where the cattle is grown before it is "processed."
Also from what these notes describe the Titans are already gone. When exactly did the Titans leave & put Odyn in charge. It seems like the Titans only gave the Keepers & Watchers instructions to create the Dragonflights & they passed that information onto Alexstrasza after the fact. Did the Dragonflights ever actually meet the Titans?
