The tree witches kept to themselves, a self-sufficient coven specializing in certain skills. The witches sang, played music, and danced at the gatherings around the fire, but nothing like what she'd experienced when the gargoyles transformed. After the first night, she was hooked.It was a risk to return but one she was willing to take. She'd ventured to that different world to hear the unique groups, especially to watch the guitarist with hair as black as midnight.
