Wei Wuxian would find the White King's skeleton amongst the ruins, still seated on his stone throne as though someone had placed him there. He will talk about the age of prosperity when all the kingdoms lived in peace and traded freely with each other. His sense of time is nebulous, and it's unclear how long ago this was. He will speak of increasing tensions with the Red Kingdom, and how the Red Queen and King wanted to unite all of Wonderland under one rule. The White King opposed their increasingly harsh methods of maintaining order and growing their own power, as they began to try to take more and more control of Wonderland itself. This culminated in a sweeping attack from the Red Kingdom, and a fierce battle between them.

The White Knights are his people, and the ruins are all that's left of the White Kingdom. Though they fought long and hard, the White Knights were completely wiped out after the battle.

If he mentions Mad March, the King will warn him to be careful.
