➰The Other Morgenstern➰

Mia is Clary's older twin sister and unlike her younger sister, Mia never had memories suppressed and Sight blocked but instead grew up learning the ways of a Shadowhunter and secretly trained her younger twin the Shadowhunter tradition to anticipate the dangers of the Shadow World than be left oblivious. Their world crosses over with the New York Institute they've evaded for a while and their goals align perfectly with the threat of the Mortal War approaching led by Valentine Morgenstern.
