The Battle of Kaladin

The central conflict that kaladin faces I find that pact that bargain and as you said that gamble that preservation made is such a beautiful one. The concept of creating the thing where he's giving up some of his power this is where we get the kalcere quote in misborn secret history about souls and human souls and metal being the same thing are that it's preservation  that gave a little bit extra to make this play against ruin.
