Finn has a relationship with Sage. Their family did not approve of this relationship, so they met in secret. Finn turned Sage so that both could be together forever.
1110 AD[]
"The Five", a group of Vampire Hunters, were created by an unknown dying witch. They are highly skilled and the spell that created them gave them tattoos that cover their arms and chest.
The witch gives them power to fight vampires. These tattoos are supposed to be a map for an ultimate weapon to destroy vampires. This weapon could be a way to make vampires human again (either that or Alexander lied to Rebekah to gain her trust).
1114 AD[]
Alexander meets Rebekah, Elijah, and Niklaus in Italy.
Alexander reveals he has the daggers to use on originals and drives it through her heart and the remaining originals.
Niklaus kills Alexander and the remaining group. Its revealed Alexander told Rebekah of a cure to vampirism. The Five were believed to been extinct since then.
Alexander's body is buried along with his sword by his former lover, Rebekah, in the church they planned to be married in.
Elijah tells Klaus that Kol was making the Originals infamous in the east because of his indiscreetness.
After he obtained the silver daggers from the hunters, Klaus left Finn daggered, who remained dormant until 2010.
