from A Call to Adventure:
The adventurers begins with a certain Lady Bella. Either she tracks down the party or gathers the characters into a group, depending on whether your players already have an operating party of adventurers.
Bella explains that she seeks adventurers to aid in the lifting of a curse laid upon her father, Count Obonos. If your campaign is set in the Mighty Land of Vanth, the Count is a minor human vassal of the Iron Dwarf King.

Adventurers seek to lift a curse by retrieving an idol from a crashed spaceship.
