Nightblood in the Well of Ascension

[JaceA]

What would happen if Nightblood, without the sheath, were plunged into the Well of Ascension?  Or what if someone used the Well and then drew Nightblood?

What would happen if Nightblood was drawn inside of a perpendicularity?

Brandon Sanderson

It depends on the perpendicularity. It has a good chance of collapsing it.

If it's possible for Nightblood to actually interact with a Shard, what would happen?

Brandon Sanderson

A Shard would try to stay very far away from Nightblood. Nightblood could not plausibly destroy an entire Shard but the Vessel could be in danger.

No idea if he could be overloaded.

[RShara]

Nightblood could eat up smaller perpendicularities. We don't know exactly how much was in the Well, so can't say exactly whether it's small enough or not. Eventually, Nightblood would probably get "full" and possibly explode into bits because he's too full, though. Since he gets pretty woozy and confused after just a few minutes of being drawn and absorbing investiture.

[Honorless]

I think the Well of Ascension has comparable or even more Investiture in comparison to the Highstorms. We see Nightblood get woozy after a few minutes of Dalinar's Unification, I don't think Nightblood can collapse that Perpendicularity.

Even if he did, there'd be Ruin to deal with, whose Investiture he's confirmed to possess. There'd be some interaction there.
