Guided by Rath'Adran, and using Tinmizer's Astounding Frost Disruptor, you have figured out how to break the frozen ice waters of the north, opening a passage to Everfrost. You must guard the ship on this perilous journey as surely all manner of frozen danger will attempt to halt your passage.
Keep on interacting with the two Tinmizer's Astounding Frost Disruptors, one at each end of the ship, until it begins to pulse periodically with a yellow halo. This will slow the monster spawns and keep their number manageable.
After several minutes of monster slaying, Rath'Adran will slowly walk to the center of the ship and reveal his true form.
Once the situation has been maintained, click on the ship's wheel to zone into Everfrost.
