Its been a while since I read RoW so I may be wrong on some of this, but this thought came up when reading another post.

RoW - All & Mistborn Secret History
  1. Do we know what happens when a godmetal is taken into the cognitive realm?
  2. We know that lower spren have a presence in both the physical and cognitive realm - do bonded spren have a visible presence in the cognitive realm when they are in the physical? In M:SH people show up as lights in the cognitive realm.
  3. if you can take one of those god metal (or inverted god metal) assassin blades into the cognitive realm, could you kill A) spren B) people using them?

    I don’t have good answers, so I’ll speculate with a bit of possibly relevant information. I hope someone asks Brandon about these, as it’s really interesting.

    1. I’m not sure, but considering that Shardblades are made of godmetal and cannot go to the Cognitive, other godmetals may be the same. Some speculation here suggests that Honorblades could travel normally to Shadesmar, which would be more applicable.
    2. Again for Shardblades, the deadeyes disappears when the Blade is summoned, so I think the spren would not have any visible Cognitive presence. That might only apply when they become a Shardblade, though. On the other hand, other fabrials, such as Soulcasters, the Sibling, and Oathgates, are still visible in Shadesmar despite having a Physical presence, so that could be wrong.
    3. I’m guessing you can kill spren with it, but I could be wrong. You could definitely kill humans, but that’s just because it’s a knife, not because of the anti-Investiture.

      For 3 I was more thinking - if people/spren have a presence in the cognitive realm while in the physical - would one of those daggers, tuned to counter the default investiture of the person kill them (in the physical realm) from the cognitive realm?

      It’s also possible that their functionality requires them existing with a foot in both worlds, so to speak. They’re not dead spren nor typical living spren. They’re willfully imprisoned in some special way. Like, the Oathgate spren are the Oathgates, and seem like they’re more responsive, but we know it’s the same process as the Soulcasters and they’re basically inert. Sanderson has said they’re something like Shardblades, but he doesn’t say they’re just like Shardblades. They do act differently and affect things differently. Presumably they just work differently.
