Survivor of Hathsin

Yes, those both sound like we are on the right track.

I'm not sure, maybe he mimicked the flesh like a kandra would or something. Maybe thats what the spike is used for. But I'm not sure. I'll have to think about that.

"Where the bones are at the end of the book is something of a mystery. They made it back to the kandra Homeland, I'll say that. However, what happened to them then . . . well, you will have to see." That was what Brandon said in a comment to the Hero of Ages chapter 52. My theory is that Kelsier used his bones. Brandon says that the bones got back to the Kandra Homeland after TenSoon uses them. He says implies that something happened to them. My guess is that he uses his bones to get his body back along with a hemallurgic spike to establish ties to the physical realm using Spooks help. What do you think? I don't think the spike is used specifically for feruchemy though, unless its Connection or something like that.

I don't think he had to get a new body. His body still had scars lining his arms, and he looked like Kelsier. I think you are right about the hemallurgy though, Kelsier probably needed something heavily invested or something like that to create a tie to the physical realm. But I don't think he needed feruchemy, unless it was maybe Connection or something like that. It makes sense why he would need a new body, though. Maybe he used his bones. Brandon said somewhere that the bones made their way back to the Kandra homeland after TenSoon was done with them. and hinted that something else happened to them. He could have used them somehow to recreate his body using Spook and hemallurgy to help him. That is my theory. Is it really unlikely?
