Nightblood theory

[labbott]

What do you guys think of the idea that Nightblood is like an investiture black hole? my reasons for thinking this are as follows. 1.Brandon has said that Nightblood is the most invested object in the Cosmere. 2. In Warbreaker when you use your breath you drain color from whatever your using until it becomes white or gray, but Nightblood is black and black can be used for awakening whereas white or gray cannot. 

so nightblood is the most invested object in the universe and it is also on the other end of the color spectrum of white. what if nightblood was so invested it became like a black hole. pulling all investiture into itself including that of the wielder... food for thought  let me know what you think

Doesn’t Vasher make a comment at some point that Nightblood would start to consume his Breaths, including his Breath if he didn’t manage to get investiture in another way?

Nightblood is the one of the most heavily Invested things in the Cosmere that is not a Shard but the Shards are infinitely more Invested and it sounds like some Perpendicularities would be in Nightblood's league per this WoB. One has little trouble imagining that Preservation's Perpendicularity (aka the Well of Ascension) would qualify as being equal to or greater than Nightblood's level of Investiture when it's 'full'.

And @imriel452 is right that Nightblood drains Investiture. Brandon has mentioned that there is in-universe debate over what actually happens to the Investiture but that his current idea is that Nightblood is doing it to sustain himself. Essentially, he's not consuming Investiture because he's a black hole but because he's hungry. Since the one thing that we can be pretty certain is around Nightblood's Investiture level doesn't similarly drain Investiture (quite the opposite) it's unlikely that Nightblood's nature is directly related to black vis a vis Awakening, black holes etc.

Would Nightblood count as its own perpendicularity as it seems to cut through all of the realms?

Every Shardblade could doing that... Nightblood is Just Better and eats the Investiture.

Perpendicularities are instead places with so much Investiture to make the Realms bend a lot.

By the way, Nightblood leaks power, of uncovered and unfeed It would probably leak to Death
