Azagirn (5E)

From publisher blurb:

Eschewing the deep, dark homes of their ancestors, the survivors of the reputedly cursed dwarven clan of Azacral now dwell amid the stark beauty of high, windswept hills. But life is not idyllic for the dwarves as their ancient enemy—tribes of half-mad, homicidal trolls— ever lurk nearby. While the majority tend herds of sheep and goats with the aid of their domesticated wolves, an unknowing, accidental threat lurks within the village—a threat that could return herald the return of the ancient slaughter and bloody death that birthed the village a century ago.
