Echo is tall, has brown skin and her eyes and nose had the typical Sand people's features, giving her a very exotic look.
Echo loved her family so much that she harbored feelings of revenge to the people that wronged her family but after realizing that her powers are useless in combat, she gave up on revenge and followed the Witch Cooperation Association.
Echo was originally a member of the Osha Clan. During a Sacred Duel four years before she set in Border Town the Osha Clan lost to the insidious means used by the Ironwhip Clan. Her father and brother were killed and the Clan was exiled to the Endless Cape. Because of her outstanding appearance, Silvermoon was sold as a slave to a merchants from the Port of Clearwater, where she spent for half a year. Before Kabago could rescue her in the Port of Clearwater, she was sold to King's City, there she was taught to become elite sex slave. She was rescued by the Witch Cooperation Association.
Echo was among the few who successfully returned to the camp after failed journey to Holy Montain. When Scroll offered to Leaf lead the remnant members of Witch Cooperation Association, the latter refused and explained she would try luck in Border Town. If she won't return Scroll should guide the rest to the south or across straits.
Awaiting group was greeted by Nightingale and Lightning and brought to the castle where a feast was arranged for them. After that Echo showed her abilities and was given room on the second floor. At night witches gathered in Wendy's room and discussed their past and future, also wondering the reason behind Roland's kindness. As the one who suffered the most from men's lust she wondered what stood behind prince's generosity. Next morning she signed a contract with him.
Soon she started practicing marching song ''Guerillas' Song''. The difficlulty was in simultaneous performance of flute, drum and string, but after several days she managed to unite them in one tune.
She met Kabago, or Iron Axe as he was called there, again when she was brought to practice marching with soldiers: he broke the line and fell to knees in front of her. After telling their stories, she was promised revenge and returned to training.
Awakening: Echo was able to imitate animals' calls.
Adulthood: Echo can imitate any sound: voices, musical instruments, cannon volley.
Evolution: Echo's magic allows her to influence the people's mood, causing different emotions. Effect depends on person's experience; people who directly experienced what was depicted in the song would be affected more.
