At first, only the Troll Tree came, but then, slowly, the others showed up too. However, they were very reluctant to follow the speech and rather made fun of the chicken-hearted Glass Trolls.
To cut a long story short, in the end they all agreed to be more cautious and reserved, and keep some of the precious stones for bad times … Anyway, they had to admit that the Glass Trolls were the only ones who still had Glass AND Precious Stones – and now the biggest pearls too! 🙂
P.S. Yes, I love stories which just evolve! 😉
