So In book 2 we are introduced to Redin, bastard son of High Prince Valam. He show up in two chapters, own a shard blade and it unofficially made High King of the Veden in his father last breath.
And then… nothing. We don’t hear from him in the next 3 books.
I was expecting him to play a role in the Veden background plot, but no, we never see him again.
So my question end up being : Did Brandon forgot about him ?
