Olivia did not know the truth about what happened between the 'Dark Sage' and the Soul Emperor during the Chaos Era; frankly, she did not care about it. She was willing to side with the Regis Clan if a war broke out because she understood their reasons for hiding the truth about Kyran's magic. If it had been her, she would have done the same. She did not have a sibling or offspring; the only relatives she considered were her mother and most of the Aureole members. But if something like that happened to the faction, she would do everything she could to protect that member.
If Lauren found the truth, Olivia would rebel if Lauren ever tried to 'do the right thing' and report the member to the Royal Army.
Then again, rebelling against Lauren was normal to Olivia, so she did not have any qualms about it. But her displeasure against the former would double.
After Byron, Olivia and Silas finalized their plans, Olivia left with her entourage.
