[Chapter] 80 [Entry] 
The kandra people always said they were of Preservation, while the koloss and Inquisitors were of Ruin. Yet, the kandra bore Hemalurgic spikes, just like the others. Was their claim, then, simple delusion? No, I think not. They were created by the Lord Ruler to be spies. When they said such things, most of us interpreted that as meaning he planned to use them as spies in his new government, because of their ability to imitate other people. Indeed, they were used for this purpose. But I see something much more grand in their existence. They were the Lord Ruler's double agents, planted with Hemalurgic spikes, yet trusted—taught, bound—to pull them free when Ruin tried to seize them. In Ruin's moment of triumph, when he'd always assumed the kandra would be his on a whim, the vast majority of them immediately switched sides and left him unable to seize his prize. They were of Preservation all along.
