The Ambassador's Secret

Award the party with 200 gold pieces should they bring Verik in alive, or 100 gold pieces if he arrives dead (treasure parcel 5 from level 1). Either way, Cressida also allows them to take a single level 3 magic item from the Citadel's resources for their continued service (treasure parcel 3 from level 1).

When the PCs accept the field marshal's request to visit Eel's End, give them a major quest to fish up some dirt on Ambassador Amprei. They are granted 500 gold pieces for the purpose of bribing the King of Spiders (regardless of how much they end up keeping, this is treasure parcels 5 and 10 from level 2).
