The Sister Mercy is a ship in the Howling Fjord owned by the Northsea Freebooters. Cursed with carrying 
[The Shield of the Aesirites], it has been forced to sail the seas unwillingly for all of eternity. Because of this curse, the boat has a catch to it; while the top deck is crewed by friendly undead, the crew in the lower level of the ship are aggressive, and are called by the captain "mutinous" (therefore they are called "Mutinous Sea Dogs").
The boat engaged with the giant they just hate, Sorlof!
In order to board the ship, one has to swim (or fly) to a tiny island where Juniper is standing. The ship goes on regular routes around the Isle of Spears and often attacks the giant Sorlof on Sorlof's Strand.

Mutinous Sea Dog- Cursed Sea Dog (it's the only lot of friendly skeletons with guns you're gonna see for a long time.)
- The Big Gun
Notes
- Before the boat arrives, you will notice there is no way to board the ship. That is because when the ship arrives, a strange ladder will somehow "magically" appear out on no-where.
- The boat is the only of its kind to use the current model of a Pirate Destroyer, making this boat one of a kind.
- This boat is also unique in the fact it's the only boat that goes around in circles with one dock (like the zeppelin that leaves Westguard Keep).
