... These forms we take-- they're nothing but... Let's call them manifestations. They're manifestations of our souls.

Sometimes, though... We "die". Our manifestations are injured, and our weapons are damaged. Sometimes, they're so damaged, that we need to be repaired. That's Failnaught's purpose. He repairs us, and he's the only one left who is capable of doing it.

But... thanks to the process, and our diminishing materials, sometimes, our memories are incomplete. We can end up acting as entirely different people, as result. You might say we're reborn.

Not that it can happen anymore, though.
