There are lots of afterlives. Which one you go to is determined by your belief system.
There are lots of ideas as to where people go when they die. What if, rather than one being uniquely true in any given world, all of them are true? In such a world, where you go after you pass from the mortal realm is determined by the theology of the religion that you follow. If you're a Christian, you go to Fluffy Cloud Heaven (or if you were bad, Fire and Brimstone Hell). If you're a Hindu, you move up or down the Reincarnation ladder. If you worship the Norse pantheon, you fly off to Valhalla. If you're an atheist, you either cease to exist or get dumped into a default afterlife. And if you're really unlucky, your afterlife isn't determined by your own faith but by the trappings of your funeral. Such a system strongly implies the existence of a Celestial Bureaucracy keeping track of everyone's religious beliefs and final destinations; it can be expressed as a literal bureaucracy or as a hierarchy wherein all of the afterlives are supervised by higher order beings who ultimately answer to the True God. Souls may go directly to their final destination or enter an Afterlife Antechamber where they're sorted and processed. In a world where Gods Need Prayer Badly, expect there to be a celestial scoring system and stiff competition for souls among the various afterlives. A Multiple Choice Afterlife directly contradicts any religion's claim to be the One True Faith, although mortals may or may not be aware of this (and, being mortals, may not care anyway). It also contains elements of tragedy for those hoping to be Together in Death, as people from different faiths are guaranteed not to go to the same afterlife and may never see each other again unless the afterlives have visiting hours or an exchange program. This can result in one or both lovers Refusing Paradise or declaring You Are Worth Hell in order to be together, although such an effort may be futile if the afterlives are totally separate.
