Original Description:
 
No. 23  
Christalia was a former changeling general who was part of the second Canterlot invasion during Equestria-Zebra war. Unable to justify to herself the changeling involvement in the war, she defected and aimed to save as many Equestrian civilians as possible. Her treachery was soon discovered, and if not for his brother breaking her out of prison, she would face certain death. Disguising herself as Twilight Sparkle, she was put in stasis by the unknowing Equestrians and sent for medical treatment inside the Equestria laboratories facility. The facility survived the bombs, but the lack of maintenance enabled Discord AI, a sentient AI with no moral standards, to take control. She must now find a way to escape the facility, and figure out what has happened.  
In game, Christalia is a mage who excels at manipulating distance. She can put herself away from enemies, while using careful portal placements to gain extra resources.
