I haven't played Wrath of the Righteous, but there is at least one sequel of sorts in the last season of Pathfinder Society 1E.
Spoiler for #10-09:
In "The Rasping Rebirth," the PCs must defeat a remnant of the defeated demon lord Deskari to prevent him from regaining power. One possible result is that one of the PCs takes Deskari's remaining power into themself. If this happens, the character becomes the new demon lord of the Rasping Rift, and inherits Deskari's portfolio. The PC is reported "dead" because they can no longer continue play, but the player gets a boon allowing their other characters to choose the retired PC as a divine patron, with Deskari's old domains.
My wife chose this path when we played the scenario, and is now playing a tiefling inquisitor of a LG demon lord.
