2000 pixel wide map, February 7, 2019.
These are the Barbarian clans I created for my campaign based on info in the expansions for First Edition AD&D.
There are 10 clans; Bear, Eagle, Star, Badger, Wolf, Shard, Talon, Marten, Buzzard (CE), and Otter.
Note: Just to make sure we are using the same word, Martin is a bird, Marten is a mammal.
The Buzzard clan lives in a rocky area, very little in the way of resources. Think of them as scavengers. Note that they are not too careful to take from those who are already dead... sometimes they assist the living into death so there will be something to scavenge.
Map at the bottom of this page: maps at this scale show generalties, not details. But the Nomad clans are mostly in the areas shown. In Teslarc; 4 areas, with 3 city-states. Land of Strife is divided by two brothers who wrestle for control of this once Lawful Good nation. One is Chaotic Evil and one is Lawful Evil.
Somewhere in this vast open area is the long fallen into ruins capital of Licieria. Yes, the circles and diamond shapes could be it. There are several of them. And maybe Licieria isn't one of the areas marked on the map.
Forests and rivers aren't marked at this scale; however, the majority of the Nomad areas are open plains.
The yellow diamond is where the clans gather for a conclave, typically every 5 years, but that isn't a hard rule. This is near the top of the map.
The full title of those lands at the top are: Place of the Dark Castle, and Kingdom of Truculence.
If the Buzzard clan is guarding anything, none have returned to tell tales of it.
Those are 200 x 200 mile squares on the map.

C. Tertiary skills
1. animal handling
a. The Wolf clan has wolves for pets instead of dogs. Most villages, farms, towns, etc. wont allow wolves to enter. You might be able to locate, now and again, an area that allows your wolf in, but don't count on this happening often. A player character Barbarian can obtain a wolf from their clan after reaching sixth level. This requires a journey back to the home clan and a d20 roll versus spell every 2 weeks until a wolf decides to join your character as a traveling companion. The player character must then spend one month of game time training their new traveling companion.
b. All other clans have dogs. The NPC Talon clan has Perrigrine Falcons. All player characters must undergo the same steps to gain their dog traveling companion, as the Wolf clan does to gain their wolf.
