A kiss from the first person you ever kissed.

Both The Reckoners and Skyward series are disconnected from the cosmere right? But what if they are linked to each other? The way Calamity viewed man kind reminds me a lot of how the Delvers viewed man kind. Calamity also said that he came from a peaceful place with much less stimuli. He also took on human form, so he used to be something else... Maybe he came from the nowhere? With multi dimensional elements added in, it could be a thing...right?
