Blackborn tribe is composed of different species than humans, though I believe you already understand that. They are planned to be like orcs, however in my own fiction and unique style. Instead of savage bloodthirsty orcs, they are nomadic cultural race with mad love for wolves and frozen plains they live in. Like nomad hunters.

Now, I believe by their laws and all they stand for, weaker and smaller ones are considered cripples in some way. But I suppose, since we're starting young, that your character is a teen, kid or whatever. It is obvious he'll be smaller than a full grown tribesman. The way I had them planned in my mind is with all that nomadic outfit such as tusks, furs and lots of ropes on their attires. When it comes to weapons, I was thinking long "two-handed" swords, axes and spears could do. Since they're hunters and all, spears can be their best fit since they have the strength to throw it far and deal massive damage on impact.

However yeah, something can work out of your idea. I kind of like it but we'll have to sync it with the rest of the bulky-men.
