Not Shallan. Not Raboniel. Though I love both of your logic. This character has sacrificed for their family. This character is in love, but we don't know if the feeling is mutual.

Love a bit of Axies. This character has sacrificed for their family.

Axies.

OK, it's been a while so here's another clue! Not Shadesmar. Not the Cognitive Realm. This place is not a place. This place's ruler recently changed. This place goes to war, but nobody knows how it is decided. This place is surrounded by warm waters.

Ethid.

I'd say Shadesmar is distinct from the Cognitive Realm in the same way that Alethkar is distinct from Roshar. However... Not Shadesmar. Not the Cognitive Realm. This place is not a place. This place's ruler recently changed. This place goes to war, but nobody knows how it is decided.

The great painter Han ShuXen! Correct!

Ooo, good guess. I suppose he does fit but... not Ati. Not Szeth-son-son-Vallano, Truthless of Shinovar. Not Hoid. Not Telsin. Not Wayne. Not Gawx. Not Shai. Not Lift. Not Adolin. This character is technically a criminal. This character believes in time limits. This character is not proud of their nation. This character taught, hired, and conspired with a main character. This character wanted their own creation destroyed. Bonus Clue: The character this person taught and conspired with is one of the incorrect guesses.

Not the Cognitive Realm. This place is not a place. This place's ruler recently changed.

Ah, the ole double feature. This place is not a place.

Not Szeth-son-son-Vallano, Truthless of Shinovar. Not Hoid. I've tried to get him to five clues before. Not Telsin. Not Wayne. Not Gawx. Not Shai. Not Lift. Not Adolin. This character is technically a criminal. This character believes in time limits. This character is not proud of their nation. This character taught, hired, and conspired with a main character. This character wanted their own creation destroyed.

Kharbranth.

Not Telsin. Not Wayne. Not Gawx. Not Shai. Not Lift. Not Adolin. This character is technically a criminal. This character believes in time limits. This character is not proud of their nation. This character taught, hired, and conspired with a main character.

The theatre Shallan uses for The Girl Who Looked Up.

Not Wayne. Not Gawx. Not Shai. Not Lift. Not Adolin. This character is technically a criminal. This character believes in time limits. This character is not proud of their nation.

Not Gawx. Not Shai. Not Lift. Not Adolin. This character is technically a criminal. This character believes in time limits.

Roight. This character is technically a criminal.

Roshar. The whole planet.

Allomancer Jak.

Silverlight.

Kelsier.

Correct! I would also have accepted the Horneater Oceans or Cultivation's Perpendicularity. Your turn!

Rayse.

@AltonicKeys Got Vasher before me. Over to you!

If it's not Vasher, then Azure.
