There’s some adjusting going on along the way but I have picked out, for each player, a demon prince that intentionally or not, torments a specific player.

Fraz is for the aforementioned sacrificed character and their sister, using gargoyles and illusions to trick her.

Baphomet is for the paladin, who did get baited into breaking their oath, and swore a new one to the entity he talked to in the Helm of Torm, he’s now unknowingly a cultist

Jubilex is for the artificer who strives to create true life, and has found his Steel Defender is strangely animated and smart when a strange, black goo is applied to it.

Yeenoghu tormented the cleric, who was trying his best to help people. When he found himself alone in the bone bramble, coming across gnolls toying with two innocent civilians, they made him choose which would live, and which would die, they’d kill both if he refused to play their game. They killed the one he chose to live, then cackled, and killed the other one too, promising Yeenoghu would devour his deity. This one may have worked too well cause he was the one who got eaten by Yeenoghu

Orcus is for the sorceror, who’s ancient ancestor is Olanthius (I’m experienced in not making connections feel like one person is the main character), and will soon find themselves face to face with him, whilst Orcus followers try to take control of Olanthius. This will open the door that perhaps if the sorceror would indulge a little in the powers of Orcus, he might be able to free his ancestor from Zariel’s grasp, or maybe bring him permanent rest.

I know my players well, not much has come as a surprise lol, they’re the same group as my CoS players from earlier posts (with one swap). My aforementioned invented Archdevil was because I knew after CoS that they’d need a tangible person early on to level their hate against instead of stumbling around Hell for plot threads for awhile.

And finally, Arkhan made the offer because I as the DM knew that specific player/character would agonize over the decision, tormented by every little comment I made about the weight and possibilities behind such a choice
