Melkor. Almost the same as he should be, unless something went wrong back in the glory days.
As for the golden scars, someone, who is an amazing fanfic author and my very good friend, told me about the facts about Kintsugi restoration art. It is used for shattered ceramics restiration. The materials are oil filler mixed with silver, gold or platinum powder.
Philosophy wise, Kintsugi art, all in all, is to exhibit the history of the object. Cracks, dents and breakouts are honorable, thus they do not require hiding or masking.
The very concept of an object with history, read: being intact for a while, destructed at a moment, reassembled later… it makes this object more valuable, comparing to its prior state. This concept really played my strings, so I had to visualize it.
My opinion, Melkor is THE natural part of Arda. And it is not really possible to erase him from this story. Otherwise there’ll be an aftertaste, a scar, a feeling, that everything is alright, but something is missing, something truly important.
All in all, I hope that there is a chance for everyone to (Webster, please help me!) revive oneself. Even for him. Obviously, he’d be about to to fix his dark deeds, and it will be challenging.
But he did not rise for nothing, after all ))
