"Ruining the Groms' War For Them"
You'll find Skelden scout Menno Heragerard on top of the mountain northeast of the Excavations. If you've already spoken with Sanno Moon, this is one of the Skelden men you'll have been sent to help in order to gain reputation with the House. (See EXCAVATIONS guide for other details.)
Heragerard says the Groms are now invading in force and fears armies of them will soon attack settlements and the Excavations.
What you'll have to do to solve this is to steal three Grom war totems from three of the four Grom war camps in the mountains, and bring them back to Heragerard. (You'll never be obliged to kill any Groms in the process.)

We decided it would be fun to maximize our sneaking skill to level 10 (which we did by solving lots of violence-free side quests in Cathalon and Quidnar before returning north), and then use stealth to sneak in and steal the totems right out from under the Groms' noses without being spotted.
However, using stealth is optional, since it's also pretty easy to simply run into the camps, lead the Groms on a run-around if they cluster together to block your entry or exit routes, and do a quick snatch-and-grab raid to grab a total of three horned totems (though you can certainly steal more of them if you want to).

If you want to travel further east in the mountains, there are also several more nonviolent quests you can complete that will also give you higher reputation with the Clan Karga:
Hagrast Wisps's Camp, and the solution to the Missing Son sidequest:
Quite a ways east of the Excavations, you can find the notorious mercenary Hagrast's camp. Hagrast will tell you that he recently killed all his own men after they mutinied and tried to murder him, but he'll never become hostile to you unless you go out of your way to challenge him to a duel.
Conn Krannach and the Idol of Throglin
Not far from Hagrast's Camp, you'll find a remote hunting lodge in the woods, which turns out to be the hideout of the Karga rebel Conn Krannach. The problem here is that you'll need some reputation with the guard to get inside to talk to Krannach, so it may be necessary to have already helped Eras Brakalet, Myron, and/or some of the Karga Fortress men like Barra, Ethan, etc before this.
After you get inside the lodge to talk to Krannach, he will give you a quest called "A Friend's Favor" in which you have to sneak into a nearby dungeon and get an idol of the god Throglin. Returning this to Krannach will reward you with more experience, gold, and reputation with the Karga clan.
