In the campaign setting book from 2008 it is described as originating in Abaddon:
> ...the waste of Abaddon stands as the source of the river Styx and is the native plane of the daemons
In Book of the Damned hell chapters it is described as originating in Avernus:
> The River Styx: The river of forgetfulness is born from Avernus and wends its way through several layers of Hell
and
> ...the ocean-sized marsh of Eridanos. Mingling with the souls of the damned, the refuse of the Maelstrom, and the eroded sediments of Hell, this noxious mixture forms the headwaters of the infamous River Styx
Except in the Book of the Damned, abaddon chapters it once again starts in abaddon:
> The so-called “River of Forgetfulness” is born in Abaddon at the Drowning Court, wends its way through several layers of Hell and numerous layers of the Abyss
Planar Adventures also places the source in Abaddon:
> Abaddon is a bleak realm—the source of the legendary River Styx
In the great beyond, guide to the multiverse we find this:
> The Drowning Court: At a juncture of eight branches of the River Styx, Charon, the Horseman of Death, rules over the floating, moving realm of the Drowning Court. [...] Lesser satellite islands routinely break away from the Court and f low downstream along the Styx’s tributaries toward the Abyss, Hell, the Maelstrom, Axis, or other portions of Abaddon
If all rivers from the drowning court are downstream, it must be the source. Except that lost omens gods and magic tells us:
> At the end of the River Styx await the rulers of Abaddon: the Four Horsemen of the Apocalypse and their daemonic brood [...] at the end of the Styx within his sunken palace, the Drowning Court
Which implies the drowning court is the end of the river? Except the same book also says
> Abaddon A vast wasteland plane that is the source of the river Styx
So what is the actual source of the river Styx? The source books are all over the place :|
