The Dink Network

I saw on an earlier post that you have to read from a scroll to lay the knights to rest. I have been all over both the normal and the shadow world, and found two scrolls. One of them says it will defeat all my enemies once only, and the other one lets me open the gate to Milder.

So where is the scroll I need to lay them to rest? And I've only found 9 knights. Possibly the one I am missing is the leader. Will I find him as the game advances, or what?

Thanks in advance!
