Dodgy Dealings

What a shocking site to behold, a dozen of dead bodies next to abandoned carriages and almost exactly in the middle of all lies a small blood-stained crate. Printed on it is an oddly shaped coin with "Waukeen's Trade" written along the inside of the coin. See notes here: 
4 Days of travel towards Lurkwood. We notice 4 Caravans in a circle next to a river. The bandits there seemingly killed each other. Ulbrinter family forged documents. Grenade with a darkling inside of it, works like a flash by killing the darkling who upon death flashes. Another box reveals a famous forged painting. Next box has a bunch of organs of creatures. The last box contained a blue breath bond. Across the sword coast it is punishable by death to forge this document. You would need to go to candlekeep to be able to find information of its integrity.
Litran Swiftfoot has threatened the party that they must give him this bond, or die a painful death. Lez should meet him alone at Boaeskir Bridge and give him the bond.
The party tried to trick Litran, yet his anti-magical machinery saw threw the illusion. The party killed Litran, but he blew up the bridge they were on, destroying the bond in the process.
Could the goddess of trade be connected to all of this?
