Mc is reborn in 16th century 1671 and his family is massacred in Spain and his family name de la vega is passed on to him.
He doesn't have memories of Tvd but does have memories of his past life he slowly gains the memories of Tvd when canon starts but does have memories of his past life.
He is then given the potential system that will be able to make him stronger by then he should be a vampire over 300 years old but he will have the ability to grow stronger from this system.
It will be au but not to much au maybe abilities here and there if suggested also maybe romance but that will also be decided in the comment section.
He will be a 'ripper' throughout the centuries but when he gets his system he will be able to get it under control so don't worry about that.
