Must that be a Devil? because I always felt that Pazuzu would work fantastic as a Big Bad for Radiant Citadel:A player in my upcoming Radiant Citadel campaign made an off-hand comment that I, as DM, am now running with.
I want an NPC who will be sowing trouble for the Concord Worlds and Radiant Citadel, specifically by facilitating smuggling guns (maybe gunpowder, maybe magitech) from San Citlan into Akharin Sangar, to help overthrow the rule of the somewhat oppressive celestial Atash. When all of this comes out, of course, it could also destabilize politics on the Radiant Citadel, maybe even leading to one or more Concord Worlds breaking contact with the citadel as a result.
The NPC will be talking a good game about supporting freedom fighters and tolerance, but they'll be actually doing the bidding of an infernal patron. So, I ask, devil experts, which named devil from the Great Wheel would be most likely to be behind such shenanigans?
That's what I ended up settling on. I'm trying to figure out how to get him involved in more adventures past the Fiend of Hollow Mine.Must that be a Devil? because I always felt that Pazuzu would work fantastic as a Big Bad for Radiant Citadel:
- He targets the most pure and good things and people for corruption, boderlinely utopian Radiant Citadel is perfect target for him
- He offers his services for pure souls and well-intended people, at first with no price, then slowly demanding more evil acts, teaching the person to rely on him and slowly corrupting them
- He is already namedropped in one of adventures.
I have few ideas, one of which is to have Pazuzu target PCs themselves, giving his name away in Fiend of Hollow Mine, hoping they will spread it among the Citadel, thus giving everyone it reaches a temptation to call on him. And seeing pretty much all leadership of Citadel is his prefered victim - fundamentally good people who are overworked, consumed by doubt and frustration about issues they cannot easy fix, thus vurnerable to be tepted with quick solution he offers - he may be hoping his name reaches them.That's what I ended up settling on.
