Who is er'ask?

Darukhar was very fond of his forest and the Rukhs who paid him homage. And even in the darkest hour, he did not leave his charges.
 
One day a disease came to the forest, which killed healthy rukhs in a few days. The forest dwellers prayed to Darukhar asking for help. The Spirit heard them and raised er'aska.
 
It was a small stone creature with a flower growing on it. From the plant, the Rukhs created an elixir that healed the sick. When the illness receded, he stayed and entertained the children.
 
But er'ask was a product of the ancient magic of Darukhar. Therefore, when the spirit disappeared, the revived stone also disappeared. But who knows, maybe if Darukhar returns, then er'ask will also return.
