Silver Mane

One of the main thing the Unull Tribe trade with other nations are their herds of massive battle wolves that are more popular and more reliable than simple horses. Also a ton more fluffier. The most influential and wealthy families of the Unull are trading exactly with these wolves. It is not easy to raise these adorable and massive creatures, but the hard labour is way worth it. You not only get an army that will scare anyone miles aways who looks at these massive doggos bare their teeth, but you will also gain extremely loyal and protective friends for life. And yes, they do get dressed into armour when it comes to battles.
The other vital trade resource that is a prideful and precious possession to have is the silver mane. When you have a herd of dogs the size of bears, you also have a lot of fur, especially during the warmer seasons as they do have the tendency to shed like crazy. And the Unull people are able to brush them all out and weave fur coats and other accessorries to keep their people warm and comfy throughout the winter. It is incredibly soft and therefore a valuable trade resource that can support not only one Unull settlement but an entire tribe, most often. It is seen as a luxury good along with any wolf teeth that are used as a powder in various medicines or as protective amulets.
Some nobles and chieftains also use strands of silver mane in hair accessories and for wigs to give their hair more volume and unique silver sheen. It is also sometimes used instead of very thin ropes and back where there were still Unull people ruling the kingdom, they had comissioned a bunch of tapestries of the Unull history that were made out silver mane instead of any golden threads that more typical for the Inzu culture.
