Also questions about the prosthetics, since /points to iron maiden man here.

So, based on the above thread, giving up something other than a prosthetic gives the prosthetics back upon entry? Since all four of Vader's limbs are prosthetic and without any of them he'd just be a stationary torso like the Black Knight in Monty Python & the Holy Grail. Which would be admittedly hilarious, but very difficult for role-playing purposes.

Similarly, I assume/hope implanted life support would be left intact?
