Norrasjosk
"Port Frostfind, capital of Norrasjo under the Arle Stormwatch. You want sailors brave enough to face ice and storm, then you want sailors from Frostfind."
Traditions
Shared Knowledge
"Sailors share what they know of the seas, not because they're concerned some other sailor will find some secret treasure, but because the seas are something they all face."
The tradition of sharing knowledge in order to ensure one's neighbors survived and would be able to help one in turn was part of how many Norrasjosk came to join the Theydim Intelligence Association or support their Arle in creating it. Times have shifted somewhat as the sharing of information has turned to be less common outside Norrasjo Arling.
Superstition
Red in the morning, sailor take warning. Red at night, a sailor's delight.
Many sailors have developed superstitions - mostly related to the weather or productive fishing - though they're generally highly personalized to the individual. No one is quite certain as to how braiding one's hair from left to right leads to a bountiful haul, but the sailors will generally refuse to give up their rituals and instead add more steps to try and appease Nature as the gods generally have no control over Nature.
Local Law
The most common form of lawful punishment is for the convicted to join the Norrasjo Navy under the belief most crimes are caused by the lack of training for a skill or the opportunity to use the training the individual has. The Norrasjo military is mostly a navy sailing out in storms to find stranded and lost fishing or transport crafts.
The eastern side of Norrasjo has a modest timber industry from the western Lognefjalls' forests, and as an alternative, many woodcutters will admit to less than legal occupation histories. Training to be a woodcutter is a valued skill set, and many go on to learn carpentry.

Death and Memorial
As the people of Norrasjo share a heritage with the people of Vetheriss, they share the sea burials, though unlike the people of Vetheriss, Norrasjo Arling has less salt and therefore do not preserve their dead. Many sailors specifically request to be sea-buried by weighing an older raft and setting it to sail in a storm.
I am curious about the spikiest whales, and I love the detail about the superstitions sailors have. It's also really nice that they share things that they know with their neighbours because they know their neighbours will have to face it too one day.

I'm glad you enjoy this article as well! The Spikiest Whale was originally an homage to another Anvilite, but this is a TTRPG setting, so maybe it'll be something to throw at players.
I also have the "sharing informaiton" policy as an explanation for why certain organizations were started here and are run the way they are.
