The Iron Hand Guild is Assassin’s Creed Shadows is a secret syndicate of merchants. There are five of them, each at a different location and as usual you only have vague clues to available to find them.

Missing Ship Merchant Kanta Location
Merchant Kanta is on the cat island in OMI.


Go the marked location on the map, as seen in the image above, and loot the broken down ship. There are enemies in the area, clear them out first. When you loot the ship you’ll get the Shipping Manifest.

Now we go find Merchant Katna in Omi, Mouth of Seta.

Merchant Kin-No-Suke Location


There is an enemy camp at this location where you need to loot the document that is the clue that leads to merchant Kin-no-suke.


When you get this letter you can start the objective to Gather intel from merchant Kin-no-suke.
The merchant is hiding in Obama, Wakasa. It is port town as you can see in the image below.

If you can’t find his location, use a Scout to mark a general location and when you get there hold down LT/R2 to use Focus mode that will help you spot a small blue dot that leads to the objective.
Unlike before you don’t have to attack this merchant. Simply give her the letter and you’ll complete the quest.
Merchant Tamao Location
Merchant Tamao is in Kyoto, Yamashiro. Again, the best course of action here is to send a Scout at this location to mark the general area and then use Focus mode with LT/R2 to spot the objective.

Tamao is near Honpoji Temple in Kyoto. He is inside a building and there is no way to get inside. However, if you destroy the wine jars outside, he will come out and you can take him down.
Merchant Ginroku Location


You can find Ginroku at this location. Assassinate him to complete the quest.
The Iron Hand Location
When you deal with all merchants you can then go after the Iron Hand. Tamba is in Tamba Highlands. The Iron Hand is inside the Fukuchiyama Castle.
