Schwarzschild Radius / Dark Matter
Matilda Seras - Mutant now Kheldian Warshade
Mattie Seras once roamed Paragon City as the gravitationally empowered mutant heroine known as Dark Matter. During a particularly vicious fight against the Council, she pummeled a bonded Nictus' host to death. It was desperate. She was exhausted and battered. After a great deal of cajoling and bluffing, and finally acquiescence, the two found themselves bonded.
The Nictus brings out her darker instincts and she curbs its worst inclinations. The newly formed being found it existed within the inescapable edges of their personalities and decided on the fitting name Schwarzschild Radius.
