So on my first playthrough I had the horrible waking nightmare quest glitch so I couldn't do any of the DS quests.
Yesterday on my second playthrough I finish the quest and go looking for more DS quests to complete but the only thing I can find are the mining quests and the Captain wayfinder quests.

Am I missing something here? Where can I find the main quest in DS? Im confused. Thanks in advance.

what do you mean with main quest in dawnstar?
there are some side quests, for example retrieving the ring for the alchemist woman and getting some void salts for the captain of the ship.
if you have done 3 of them, you will become thane of ds but i guess thats it.
and there is the quest with the dawnstar museum

Dawnstar has no other quests.

You can get the two Daedra quests and the typical radiant quests from the jarl and the inn keeper.

Ok thanks. Well I expected so much more.

If your looking to become thane, cop wood and take the guy up on offer to fight you, thats the other 2 I choose.
