Hey guys, I'm new here so I'm sorry for bumping this thread but I just finished the book and this is all fresh to me.
So, the book obviously leaves a lot of open questions (16 alloys of the god metals?) and Bloody Tan is definitely part of the puzzle it offers us to solve.
While I like the idea of Bloody Tan burning Chromium, I just don't see it fit the bill. I.e. without Duralumin there is no reason why Tan would've run out of luck at that very moment. I also feel like he allows himself to be killed afterwards and that being lucky doesn't mesh with the other information we're given in the scene (i.e. his insanity).
I much more feel like there is a god metal involved. Either in its own or an alloy of the two. The insanity of Bloody Tan gives us the best clue I think because the way he keeps claiming that they're all "puppets" hints a lot towards Atium. A person who's burning Atium could very well lose his mind after seeing for too long that everything is already planned out for some great cosmic play. Heck, I almost turned crazy after turning to Determinism as a teen.
I rather like the idea of Bloody Tan having been a previous "champion" of one of the battling sides (there are probably more than we know of). He is not an Atium misting per definition which still leaves open that he's either got access to more Allomantic abilities, that he's burning an alloy or that he's using Hemalurgy in some way.
The next book is going to be a nice read.
