Guess the...

[Curiosity he/him]

It is Cosmere. The initial hint can be interpreted two different ways, but only one is correct...

[gjustice99 she/her]

in the Palanaeum?

[Curiosity he/him]

Nope. But you're in the right Shardworld.

[Jo and the Bush all/any]

I don't think any of the characters have a grandfather mentioned. Shadesmar?

[Curiosity he/him]

Not Shadesmar. This location never shows up onscreen.

[Jo and the Bush all/any]

Herdaz?

[gjustice99 she/her]

the hospital?

[Curiosity he/him]

There is nothing about this place that is conducive to hiding your grandfather. 

[gjustice99 she/her]

Urithiru?

[Curiosity he/him]

It's a bit more subtle and obscure than that.

[+Slowswift]

Tranquiline Halls or the afterlife or whatever they call it?

[Curiosity he/him]

Nope.

[+Slowswift]

So "not conducive" means you wouldn't want to hide your grandfather there?

[Curiosity he/him]

There's nothing that makes this place an excellent location to hide your grandfather. 

It's not as if the hint is "A good place to hide your gold" and the answer is "A Swiss bank". 

Perhaps the "answer" is closer to "a thieves' tavern"

Yes. That was what I was looking for!

[+Slowswift]

Yay! 

 

No one loves him as much as she does.

[gjustice99 she/her]

Vin for Elend?

[+Slowswift]

Nope.

[mail-mi he/him]

Lopen's mom?

[gjustice99 she/her]

Siri for Susebron?

[+Slowswift]

No and no.

No. Hint:  One is a character, the other's a fan... 

[gjustice99 she/her]

Feather for Renarin!
