Not something they wanted to do. Fishing. But it puts food on the table. And some people, particularly those on Grain Isle, like halibut.
And they will trade such fish for grain and beef. They like the swords, shield, and maces the dwarves make as well.
In the winter months these dwarves fish for cod and albacore south of their island.
They say it is their island, but they stay away from Shadow and Little Shadow. Two megaliths on Fisher Isle.
They, and a group of humans, built Ball Lock Tower and Ice Castle.
The tower on the other end of the island has long been abandoned. And yet lights can be seen shining inside from long distances away.
Those who live in Blue Castle, on Bis-Cha Isle, have reported seeing lights across the way, even though that lonely tower is miles away.
