Two unnamed Vampire and Vampaneze children

These two unnamed Vampire and Vampaneze children were the children of Lady Evanna, Vancha March and Gannen Harst.

Sons of Destiny
In order to trick her father, Evanna agreed to bear a child or children of a Vampire or Vampaneze if he allowed her to go to the wasteworld to pull Darren Shan out of the Lakes of Souls. She later reveals that (to prevent the Vampires and Vampaneze from losing the peace treaty in progress) her children are twins and their bloodlines will be split into one third Evanna one third vampaneze and one third vampire.
