For whoever would like it:
Locations (only) are based on "Encounter at Blackwall Keep" from Age of Worms, which my group played through as being in Eberron, per the notes by Kieth Baker.
To Kill A Toad
In a swamp near Sharn, two small keeps have been built to discourage lizard men raiding on their more civilized neighbors. The soldiers recieve their pay once very 3 months, delivered by a smal militia troup. Recently, the majority of the troop retreated from the swamp in disaray with the news that their leader (who was carrying the pay at the time) was swallowed whole by a gigantic toad (mmII p. 76.) The rest of the troop fled. The militia is looking for a group of adventurers willing to hunt down and kill the toad, and is willing to give that group of adventurers the details of te ncident (including te specific location) in return for a promise to return 1/4 of the pay to the militia. The remainng 3/4 of the gold will be the reward for the adventuring troup.
Other dangers are known to lurk in the swamp, and the militia is very concerned that the party not stir up the lizardmen, with whom they have a truce at the moment.
