Sarting quest: Slaves to Norvelland

The party received an invitation from a new inn that is opening, it's supposedly grand and luxerious, built with new resources and a great symbol to Etherian greatness even after the sunder. The players party and drink and eventually wake up in the basement of a slave ship, heading towards Norvelland, the last empire that uses slaves. The party needs to escape or take control of the ship.
When they escape or take control of the ship the players are able to get to the closest shore which would be the shores of Everia, close to the border of Gol. At the cliffs of Gavallia

Ship:

The ship is made of 3 floors, the Lowest is filled with different sizes of crates filled with construction materials, like timber, nails etc.
in the centre of the floor is a cage where the players are put in. The players are besides that chained to the wooden floor with a metal chain around their ankles, so they'll need to open the cage and break their chains before they can escape.

The second floor is where the crew sleeps, but it has enough walls and doors that players could sneak past them to the next floor if they wanted. If a crewmember gets alerted he would try to alarm the rest if he is able. This floor would also have a chest with some extra equipment for slavers, which could be used as weapons for the players.

the top floor is the deck of the ship, there will be often some crew members walking around, maintaining the sails and steering the ship. This deck also has two emergency row boats tied to a rope on the sides of the ship, these could be used to escape the ship.
