“This is how it feels to be Anakin Skywalker, forever:
The first dawn of light in your universe brings pain.
The light burns you. It will always burn you. Part of you will always lie upon black glass sand beside a lake of fire while flames chew upon your flesh.
You can hear yourself breathing. It comes hard, and harsh, and it scrapes nerves already raw, but you cannot stop it. You can never stop it. You cannot even slow it down.
You don’t even have lungs anymore. Mechanisms hardwired into your chest breathe for you. They will pump oxygen into your bloodstream forever.
Lord Vader? Lord Vader, can you hear me?”
