Conventional wisdom would suggest that all Devils are in league with one another – this is not the case with Asmodeus and Levistus.
Years ago Levistus had set in motion a plan to usurp Asmodeus’ control over the nine hells of Baator. Asmodeus as usual was one step ahead – and despite their best efforts, Levistus’ plans were foiled. Now Levistus finds themselves imprisoned in Stygia, and works through their agents to facilitate escape.
This is why our heroes find themselves in the middle of infernal politics.
Klondorn believes the codicile can be used to free Levistus from their prison. To prevent this from happening he has begun badgering our heroes to hand over the tome now that they’ve used it for their intended purpose – opening the way to Ythryn. He has dropped any pretense of being a ‘normal’ inhabitant of the Dale but the exact nature of his status in the infernal bureaucracy is unknown.
