   Summary

   For the past year or so, Doctor Eggman's antics have gotten more and more intense despite all the grace he has given him. Sonic isn't sure much more rope he can throw. Their current adventure has been full of twists, turns, and close scrapes, but devoid of any kind of answers. As they enter their final battle, Sonic, Tails, Shadow, and Amy have no idea what they're up against.

   Eggman has gone too far.

   ---

   A story mainly focused on developing and exploring the characters and their relationships because its fun. Sonic is at the center of it all due to his role in the inciting incident that was the straw that broke Sonic's back.

   This fic mainly follows Sonic, Tails, Amy, and Shadow, with Knuckles and Rouge as supporting cast. Sage, Eggman, Metal, Orbot, and Cubot have some chapters to themselves as well! :D
