It Never Rains in Nyrond

Description from the front page of the module: With the constant pressure and sorrow that Eastfair extrudes, even the most stout hearted can get the blues from time to time. But missions must be completed and duties upheld with little time left over for lamenting on greener grass. Now an old friend needs you to carry on where others have failed. A package needs to go from point A to point B, and even with a severe storm brewing, this side trip should not take you far out of the way of your own destination. Said destination being that of the instigator of all this. An adventure for APL 2 - 8. Part Four of the "Running with the Baatezu" series.
