Chapter 787: Those Who Stand Among Us. 2
Looking at Maya and Leona, Vlad noticed how Elizabeth's blood remained firm and strong. The mutation caused in Elizabeth's blood was so dominant that even members of The Lykos Clan who had children outside the Clan would have the same characteristics of The Clan: white snow-like hair and sky-blue eyes, though in some cases, even emerald green may appear.
It could be said that The Lykos Clan genes were predatory; no matter what Race you belonged to, if an individual was from The Lykos Clan, the blood of The Clan would always prevail. Even the Blood of a Progenitor or a God would not affect the Lineage of The Lykos Clan.
The reason for this was due to the 'enhancing' properties of the Progenitor Blood. Taking Vlad's children as an example, all of them, without exception, had the blood of the mother's side enhanced thanks to the Progenitor Blood.
