I am likely not using the correct word. However, when Sun spoke to me, he said that I should be able to figure out why the Marked are marked in the first place with the evidence around me.

What I am trying to convey is that there must be something that we can find, either through Travelers' memories, or through the spaces around us that will tell us more about what we are dealing with.

This entity is important, of that I am certain. However, where it fits in the larger puzzle, that is unknown, and a bit worrysome.
