Flight of the Valkyrie

Background

The year is 301 PS (Post Scouring). You are playing a group of inventors who work for the Gearworth Steam Tech Company, either as an employee or a contractor.
The Gearworth Steam Tech Company has finished construction on the first ever inter-continental class airship, which happens to be their first airship (as far as the public knows).
There have been other airships created. Hollowholt, before its destruction had many airship. And Insomnia City has made several airships.
The party has been assigned to protect the new airship, call Valkyrie, on its trip. The party is to maintain the airship's systems and protect it from any external threats on its trip to Noxhaven.
The trip from Oros to Noxhaven normally takes 30 days via boat. The trip via air is planned to take 15 – 20 days.
The specific goals the party are assigned with are: 1) Ensure the airship makes it to Noxhaven, fully intact and cargo secure. 2) Make sure the airship is airborne all the way from Gearworth to Noxhaven. The airship should only land in the case of an emergency, as that will fail the concept of being an inter-continental airship.
