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
- Do we know what happens when a godmetal is taken into the cognitive realm?
- 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.
- 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?
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?
