Even the dwarves, who excel at mining, have to admit that the talented Gnoll miners are always the best-suited workers in the mines. Therefore, in the territories of the dwarves, the living conditions of the Gnolls are much better compared to other areas.
The dwarves always periodically select miners from the Gnoll tribes to send into their mines. It is said that the Brass Dwarves even developed a costly "Eternal Candle" for this purpose.
That is the most perfect gift a Gnoll could receive in their lifetime, only those old foremen who have served the dwarves for over twenty years without dying could possibly get this kind of reward.
Of course, the Transia People don't have the expensive Eternal Candle to trade with the Gnolls, but that doesn't stop small players from using their imaginations.
