Andrew is a down-on-your-luck dude working for a store in a small city in Vermont. On the same day that he gets a notice that he's got to pay a late fee on his rent, he is invited into and enters a tent owned by a man whom he assumes is homeless. It turns out that that man is actually a random omnipotent being (or a R.O.B. for short)! The man offers him his choice of any number of essences, potions that give him superpowers. In exchange, Andrew has to agree to go on a journey, a jumpchain. 

Andrew decides to say yes and kicks off our journey into the multiverse. His one catch? He drinks every potion that Ben, Andrew's benefactor, has on display. Hundreds of potions. And in doing so Andrew becomes a super being, who'll get to explore thousands of distinctive worlds and go on countless journeys throughout existence.

Ben is a bored, mighty, random omnipotent being. He gives Andrew his pick of a treasure trove of essences, powerful potions that grant their drinkers an incredibly diverse array of superpowers. 

All Ben seems to want is to be entertained by the adventures that Andrew will inevitably embark upon, as a consequence of having opted to imbibe the man's essences. Ben is Andrew's first friend since he's become an essence-empowered entity and is excited to watch over the jumper as his benefactor.

Almalexia was a member of the tribunal, the body of divinities that ruled over Morrowind, a region in the continent of Tamriel, on the planet named Nirn, in the Elder Scrolls series. She was once married to Lord Indoril Nerevar, the man who'd unite the civilization that would one day become cursed by Azura and become the dunmer. Almalexia becomes a goddess by stealing power from the Heart of Lorkhan and is eventually slain by the reincarnation of her husband, an enigmatic entity known only as the Nerevarine. 

The middle child and one of three daughters of Julieta and Agustin Madrigal. Her sisters are named Mirabel and Isabela, and Luisa herself is a possessor of a rare and powerful magical ability known as a "Gift". Her "Gift" is super strength. She is the backbone of her generation of Madrigals. 

Essences are potent items created by powerful entities. These entities need not be as vastly mighty as a random omnipotent being, but they do need to be powerful themselves. Essences grant their imbibers a plethora of superpowers and are always backed by the person who brewed them until those who imbibe them have enough power to back them themselves. 

Any being, no matter their individual level of strength can imbibe an essence. Essences can do anything from giving someone infinite money to giving someone a spark of divinity.
