The Fate of the Damned festival has you running all over the Sea of Thieves completing tasks to hold back the tide of the Ghost of Lord Graymarrow. There are several beacons you need to light each week, and for the Fire of the Ancients challenge, you need to light the beacons located in The Ancient Isles. These beacons require you to use a blue or white flame of fate.
To receive the blue flame, you need to die by a shark and then collect the fire from the Well of Fate on the Ferry of the Damned. To receive the white flame, you need to die by lightning.
These are all of the beacons you need to light in The Isles of Ancients.
The first beacon you can find is on Crook’s Hollow. The island is on map tile M16. You can find it on the southern portion of the map. You do not need to be fired from a cannon to reach it.
The next beacon is on Devil’s Ridge. The island is on tile P19. You can find it next to the island’s waterfall.
The final beacon you can find is on Plunder Valley. The island is on map tile G16. It’s at the top of the island. You do not need to use a cannon to get there, but it takes some walking.
