Role in the Series
Besides what's coming in the future about her, she is later revealed to be the long-lost older cousin of Hidden Shadow, who was a war veteran for the Equestrian Royal Guard after her father and Councilpony Cometelius's war-instinctive and war-damaged sister Aphelion Shadow, who despite also having a broken horn, has been trying to defeat Storm King for years since he enslaved Tempest with no success. It's later revealed that Cometelius' real last name was in fact Shadow until legally changed after marriage because his wife found it nice since it was his mother's maiden name.
