Detailed Walkthrough
After sailing to Haven, you will find yourself on deck of the prowler amid the aftermath of a fierce battle. Talking to Captain Jimila reveals that Haven is besieged by pirates. You will need to jump off the deck and into the water to find Lieutenant Kazargi on the beach northeast of the Prowler, amid a group of refugees. When you talk to her, she'll recognize the Prowler. She introduces herself as a soldier in service to Lord Gharesh-ri, the Speaker for the Mane. Lord Gharesh-ri left some time ago to retake the city from the Jackdaws, the invading pirates. She doesn't know where he's gone off to, but she points you in the direction of Naaril, a merchant, and Curinwe, the woman leading the fisher-folk who live here.

Naaril can be found just east of Lieutenant Kazargi, sitting at the campfire. Curinwe can be found north of Lieutenant Kazargi, guarding a stone archway leading into the refugees' camp on Fisherman's Isle. They both tell you that Gharesh-ri crossed the marsh and entered the city, noting that he should be near the gate.

To find Gharesh-ri, go northwest. There is no path, and the swamp is filled with Hoarvor. Along the way, you may find Eryarion, who will give you the quest Lost Treasures.

Upon entering the city of Haven, you will notice that a number of Ghaja's Fangs have fortified a house just in time for another attack by the Jackdaws. Inside of the Abandoned House, you will find Lord Gharesh-ri with a small contingent of Fangs. Without the luxury of having large numbers, Gharesh-ri must resort to more subtle means to retake the city. He suggests that you find crucial members of the Jackdaws' crew and retrieve your orders. You can eavesdrop on them, or kill them and steal their orders. Gharesh-ri insists that if the people you're looking for are important enough to the pirate captain, they'll likely have written orders nearby.

Two of the Jackdaw Lieutenants you are looking for, Artificer Hlana and Warleader Yngold, are both west of the Abandoned House. Jeer-Tei is located south of Haven on a boat. Hlanas' orders are apparently to obtain materials for a ritual from the Mages Guild. Yngold's orders demand more corpses for some kind of necromantic ritual. Jeer-Tei's orders are strangest of all, demanding that a drugged wamasu is brought into the sewers below the city.

Locate the entrance to the Aquifer. You will find it just northwest of Jeer-Tei's ship, Lieutenant Kazargi will already be there. Tell her about the Jackdaw's plans, and she suggests you go through the sewers and find a way into the fort from there. She'll grab Gharesh-ri and inform him of the pirates' scheme.

The Aquifer's entrance is a sewer tunnel just beside Lieutenant Kazargi. You will find yourself at the southern end of the complex, and have to find your way to the north. There are many Jackdaws and hoarvors in the Aquifer. In the final chamber, you will find a giant wamasu named Tsonamot being tended to by Beast Handler Mahei-Ma. Killing them is optional. In the chamber behind them is a rope that you can use to climb into the fort's gatehouse. Unlock the gate, and talk to Lord Gharesh-ri just outside.

The pirate's leader intends to flood the streets of Haven with the undead. They are conducting a ritual in the abandoned Fighters Guild hall. You need to enter the hall and disrupt the ritual while Gharesh-ri and his company distract the pirates outside.

Though Gharesh-ri claims that the Fighters Guild will be heavily guarded, the building will at first appear to only be inhabited by Gjarma Raven-Hair, and it is only after you defeat her that the necromancers and their focus crystals appear. Destroy the three focus crystals and exit the building. Lieutenant Kazargi lies wounded a little ways down the stairs in front of the guild hall, and she appears to be gravely injured. Regardless of how you respond to her, she is glad to have fought beside you, and tells you not to let Gharesh-ri worry about her.

With the invasion quelled, you should inform Lord Gharesh-ri that you defeated the pirate leader and her plan. He will be pleased with your success.

Once you have finished in Haven, you may follow The Great Tree to Elden Root. If you have arrived in Grahtwood without picking up The Great Tree, you will be offered Trouble at the Tree instead (these two quests are mutually exclusive).
 

Bugs
 
ZOS reports that this is working as designed in that, due to certain system limitations, it cannot be easily fixed.
Setting a different quest to your active quest and then changing back to Unsafe Haven can be enough to fix it.
 
Don't go through that upstairs door; it is permanently locked from the outside, and you'll have to jump down and run around to the town wall entrance to get back in. Instead, go out the same door you came in, finish the other quest steps there if needed, then go to the north section of town by the fountain to find Lord Gharesh-ri.
