Sweetroot is very underrated. Do you remember when Star and the others ate poisonous berries and almost died? Who was there to save them? Sweetroot. At the beginning in Starfire she was the one to help with his dragging wings. Even if she was not the medicine mare she was still very loyal to Star from the beginning to the end. She was the oldest mane charter that lived through all the books (Rip Mossberry and Grasswing.) That just proves how strong she is. I can't name how many times she has saved everyone from certain death. So that is why she is one of the best charters vere.
