Note
It turns out that Asmodeus has been quietly targeting some of Faerûn’s most powerful figures from the ranks of nobles, wizards, clerics, heroes and adventurers.
Over the years, the dreaded demon lord has made pacts with these individuals (including the player characters), coming to their aid in times of need in exchange for their souls. Now, he’s sent an army of elite assassins throughout the Realms to kill these individuals and send their souls into his dark embrace.
When the adventure kicks off, the players find themselves in the Nine Hells. They’re forced to choose between the various factions battling with and against Asmodeus himself. Along the way, they’ll encounter powerful infernal monsters and unholy magical relics with the power to reshape the underworld itself.
