The person I was secretly following was a woman named Dane. She was formerly a member of Astley's Paladins and apparently a unique skill holder. After the revolution, she joined our military, and she had been training her body vigorously since then.
When asked about why she joined our military, she just said that she still had a long way to go after seeing a fraction of our power. She originally planned on retiring, but she changed her mind to pursue greater strength.
As a renowned adventurer, many recognized Dane, and they were surprised by her comeback after her retirement. However, nobody but our family knew her identity as a former Paladin of Astley.
She was the most powerful, in terms of Level, among our knights and soldiers so far. Michael, Lucy, and Uriel had been suppressing their levels and skills, so ostensibly, Dane only surpassed them in terms of current stats.
