Pebblekin

Overview

The Pebblekin dwarves are another ethnicity originated from the Stonekin dwarves. A few of the dwarves came from the Copperkin clan, but who is counting, right?

After their falling-out with the Stonekin clan they searched for a new home and found it in and under the molten rocks of Eldurfaðir, the Fiery Father at the Daveldare Mountains.

History

The history of the Pebblekin is relatively short. They are not really noteworthy besides that they live inside a semi-active volcano, but their products are. They had two leaders, now their only leader is a female dwarf called Irdrá.
They needed a new home after the falling-out and their scouts found an entrance to a cave which ultimately led into the underbelly of the volcano. The holes, caverns and naturally formed tunnels after the lava got cold were the best - and most intriguing - they could've hoped for.
Then they found the hot springs and the Obsidian.

Moar pebble products!

At first their currency Jótskýfa (in Common Speech "Stonecut") was established, but got eredicated really fast by the Forgepiece of the Golden Hoard Capital and Investment Management. The Pebblekin were a bit mad about it because they have established an entire production line for the pieces, but it is what is is. No need to argue with all other clans and the Dragonborn.
Then they discovered how to create Obsidian. How to work with it, how to craft weapons, armour, pottery and items used in the household with it. Yes, Obsidian armour can't take a beating, but if you forge your standard issue of armour and coat it with Obsidian, you are probably the fanciest motherfucking dwarf. Or rather dwarven army on the battlefield.
In terms of weapons... well, weapons crafted out of or coated in Obsidian are not very sturdy, but they are dang sharp. The arrowtips or tips of crossbow bolts are made out of Obsidian and yes, they can't really penetrate a lot of armour - chainmail is a good example of what they can penetrate - but the fragmentation can cost you a piece of your face, your entire eye or something different. Fragmentation inside your body is a whole different topic, which makes the Obsidian arrows so highly dangerous.
Since every clan has a mushroom to call their own, lets talk about the Grey Everleaf, shall we? It is a colony-based mushroom with up to ten shrooms per colony. They move around and have some kind of intelligence and you can make a very tasty drink and soup or sauce out of them. In the Dumpling Exchange they are more the side dish or the sauce than the stuffing of the dumplings.

Obsidian Pottery is another thing. One can buy the pottery in two variants: entirely made out of Obsidian - entire pots or bowls - or pots or cups with fragments of Obsidian baked into the clay.
But the Pebblekin clans wouldn't be a good dwarven clan if they wouldn't do anything honourable, aye? So they crafted out of the hot mud springs their licensed (they say it, but it isn't licensed) Pebblekin Beard Mask. It is made out of the mud of the hot mud springs, enhanced with herbs like mint or nettles. Even dried out one can "revive" it with a bit of water so a beard can grow and smell nice while doing so.
And last but not least they have a bit of tourism because of said Hot Mud Springs. They are an area inside the volcano a bit on the side of the underground city. The springs are divided into two areas: the private ones and the public ones. Public is basically bathing, relaxing, talking, unwinding from the daily business. Dwarves and tourists use it for... well, everything. The more private areas are for long sessions like mud baths, massages, private gatherings. Guests can choose between company, ingredients, beard oils, different types of massages and herbalist oils and soaps.

Pebble Tales

"Here, look at them doofus." Fredrá pointed out a colony of Grey Everleaf. They had seven mushrooms in a colony and all seven of them were leaning their hats into the middle of the knotwork. "Me not know what they're discussing, but me don't wanna know, to be honest."

"I find it very fascinating that every dwarven clan has their own... signature scent?" The man shrugged. "Not one scent, mind you, but the Pebblekin smell always nicely fresh and clean while the Stonekin dwarves have this heavy amber smell, ya know?"
