"Adsila: Ancestress of the Wood Tribe" by Samantha Manpher Keene

I have quite a long story behind this character. Too long for one sitting so I'll be brief.

This is Adsila, a minor character in the story of Nintow, a child savior. In the world where Adsila lives there are humans, the various plants and animals and the rare Intermediaries.

She is an Intermediary for all things of the forest, morphing into the bark of trees. She fell in love with a human woodsman and left her people. From her offspring came a tribe with dark bark-like skin and red hair with a speacial connection to all plant life. Her human husband is one of the four statues that Nintow collects. Also among them is the Wolf, the Bird, and the Cat.    

I can't wait till I have more characters from this story. The Child Nintow is one of my oldest and favorites.
