time and creativity, in their universe, are deities. they're referred to by their representatives as "Their Divinity" and "Their Sanctity" respectively!
anthony and paige are the representatives of time and creativity. they work like prophets, setting out to spread the teachings of their subjects however they see fit, and...paige & tony have a very violent way to do that!
how representatives are selected by these deities is that they have certain criteria as to who is worthy to represent them. it's usually someone who is passionate and devoted enough to something that relates to the subject (such as a painter, a horologist, etc)
if someone meets those criteria, the deities offer them the position. if the person refuses, their memory of the proposal is erased and they live on like normal. if the person accepts however, their memory is wiped and they are physically altered to suit their gods' image: accurate to how they used to look with special touches
this means that both paige and tony had past lives but don't remember anything at all about them. the only thing that passes down during this transfer is their disposition and personality.
time is a strict and objective god, dealing in data, facts and strategy. overall, they embody the "left brain"
creativity is very emotion-oriented and lenient, as well as serving as a muse when it comes to inspiration. the "right brain" to time's "left brain"
this isn't to say they're foreign to the opposite's thinking ofc - time has emotional understanding and creativity balances logic as well
