Historical: Liberation of Terra Volume 1 and Era Report:2750 has conflicting info about Nicoletta Calderon.
One says she was born in 2707, the other says 2708.
One says she became protector in 2725, the other says 2726.
One says she was niece of Hampton Calderon, the other says she was his daughter.
Considering the Lorix issue in ER:2750, I am more willing to trust Liberation of Terra, unless you rule otherwise.
