Not sure how many people are still running this campaign, but I'll drop in my own usage of Sial.
Long story short: it didn't last long. Literally minutes after he introduced himself and his chain-devil companion Asyra to the group in the Acropolis, the cleric of Cayden Cailean channeled good and initiated combat. This was much to the delight of the barbarian, who wanted to fight things anyway, and the rogue who just wanted all of Sial's stuff to sell.
He attempted to escape the raging, crit-mongering barbarian, and in his haste did not cast his "word of recall" scroll defensively. The barbarian hit Sial against the wall, and sliced him in two with his greatsword.
The cleric is now thinking about using the word of recall scroll to go on the offensive with the party. It says the scroll goes to "Sial's house in Nidal." Any cunning DMs have any suggestions on where to go from there in terms of sidequesting? I could make his house be all trapped and contain more treasure, or I could make some kind of adventure hook in Nidal.
Any advice and/or suggestions would be greatly appreciated!
