How to run the "Skull of Destiny" voyage for the Ghoul & Glory event?

@jovial-dorp Well you should automatically receive Skull of destiny voyage in your inventory. Then you will receive a compass which will lead you to the skull.

Once you dig up the skull, sail to the fort of damned. Park your ship there, bring the skull up, and light up all the lanterns with the correct color. Once done a cage will open and you will be able to put the skull on a skeleton. Once done, the fort will start and will act as world event, everyone in the server will be able to see that the fort is active. (Skull with red eyes in the sky). After which skeletons will spawn, but they will require for you to take out your lantern and shine the correct light on them to make them vulnerable. After countless waves of skeletons and captains, Graymarrow - boss of the fort will spawn. After you defeat him, he will drop a fort of the damned key. Use it to unlock the vault below.
Then it's up to you how you get that loot to your ship. Most players place the loot around the sticking out pole or drop them on the rocks and then harpoon everything.

P.S. Keep your eyes on the horizon, look for rowboats and mermaids around the fort.
