The creation and construction of the suit had been perforce hasty, since the maimed and burned thing that had been Anakin Skywalker was dying, and would not have survived for long even in a bacta tank. There had been no time to tailor all the life-support systems specifically to his needs. Many of the suit's features were adapted from earlier technology, such as had been designed for the cyborg droid General Grievous over two decades before. It was hardly state-of-the-art. It could, Vader knew, be rebuilt now and made infinitely better, more comfortable, and more powerful. There was only one problem with doing so: to be completely excised, even temporarily, from the suit would kill him. Not even the safety of the hyperbaric chamber-indeed, not even his command of the dark side-could ensure his protection during such a procedure.

Like it or not, the suit and he were one, now and forever.
