Maria is the scientist mentioned in https://www.furaffinity.net/view/54826112/, the one who grew the creation Goddess Synthia in a lab before the collapse of the doomed universe.

She ended up surviving the collapse, and she herself became one of the perennial, a deity who came to be from surviving the collapse.
She grew to become the deity of time and luck, and can manipulate both in her favor.

People who are hero level can pray to Maria to gain protection from death, if you die on a day you prayed to Maria your consciousness will he transported to a pocket dimension, and into a clone of yourself where you will be locked in a stark white dungeon full of trials and puzzles, and once you complete all trials you will be brought back to life is a blast of sparks and energy.
But if you forgot to pray that day, straight to some sort of afterlife, which is much harder to get out of.
