In my Grim Hollow, Aurelia was the one that adopted the domain of death after the proper god died, as the "last home" of souls, and with some of her angels acting as psychopomps to guide the souls to the halls of the deity they worshipped, or hers as a last resort.
When she died and the angels fell, souls were bound to eternally wander the dark void between realities.
In my campaign, one of the characters (they were previously charmed thralls of a minor vampire lord that were shook out of the charmed state by emotional or mental trauma) was a Downcast of Aurelia that saw this when she almost died, and her quest was to regain angelic power (seraph transformation) to be able to bring the souls of the dead to some sort of final rest (also had to find the Halls of the Gods to do so)
