The final stage of the process at this point you can confirm that's all done with the Whaler, before he asks you to simply go fetch his brother, which'll take a couple of moments at most.

Head back to the Whaler, then fetch the Hermit.This time you can approach from the North to do so, but remember to watch out for that bloody fish! Just approach and interact with the wall to get the option for demolition. He won't give you any explosives for this, they're already set up and just need lighting. Show him the Crest and he'll ask you to blow up the target wall that obstructed you earlier. Bring it back to the Whaler in Ingfell.The spot with the Crest is marked by a gold glow in the very centre of this open area - get it quick and get out of there! Obviously you'll need to know how to dredge in Dredge to do this, but by this point, that should be something you've got handled. More details below if you want help with that. Exploring isn't as easy as it should be - beyond the falling rocks and sudden geysers, this is also the hunting ground for a giant one-eyed fish, visible beneath the water from the red glow its eye gives off. Avoid the one-eyed giant fish while travelling.You'll deal with those later, but for now go around the island to the nameless dock at the South, then go up towards the green marker we've put down. The obvious route is actually cut off by a string of rocks, marked in red on the map above. Go to the open bay in the centre of Gale Cliffs.Between the two of them, you'll learn that they're brothers, and while the hermit wants to see his brother, he can't without the Family Crest. Head to Ingfell and talk to the Retired Whaler, then the Ruins to talk to the Hermit.Here's a basic how-to to take you through it. Once you reach Gale Cliffs, you need to complete a quest called Hermitage, which will end with explosives being sold around the map. You don't want to go there straight away, as you'll need a faster engine to safely cross the open ocean, but after you've upgraded once or twice you should be able to make the journey. Explosives in Dredge are obtained from Ingfell’s Retired Whaler, in Gale Cliffs, Southeast of the starting area.
