"In your travels, you will come to witness things that are more beautiful than anything you will have ever Observed previously. You will find brilliance of previously unheard of levels. You will find understanding of things that most of Us strive our entire lives to find. Perhaps you may even find a Species capable of being Our successors, a Species that we may bestow the Mantle to when We Ourselves are gone.
"There is a price, however. Like everything else, there must be an equilibrium.

For every brilliant thing you discover, you will find equal amounts of dementia and ignorance. For every understanding, there will be something that you simply will not be able to answer.
"Do you accept the Title of Curator?"
