Wild Berry Meadow I will never disappear

"A healer then, eh?" Hedda's interest was sparked, when the girl mentioned having herbs and plants stashed somewhere. Most people learned only the very basic stuff about the plants during their lifetimes and therefore it was no wonder that in times of famine they died of hunger just because they had been ignorant enough not to see the other means of food lying just around them. For this reason the old hag had sort of respect to those, who showed skill and knowledge in the field.

And she was offering a trade - still undeterred by the elder's horrible appearance and bad character. Which reminded her of the very last task her master had given her, before he claimed her soul. Tell the story, pass on the knowledge... and she was very much aware of the fact that her time was running out. Not dead yet, but nearly there. 

"Plants won't heal me and the won't feed me either," she finally replied. "Let's make a deal - for every piece of food you bring me, I teach you something. The more often you bring, the more likely the lesson will be longer."
