BOOM!
The big Vampire got pushed back from the colorful fire expression that exploded from both Evelyn and Adhara's bodies, their already strong physical properties got enhanced by mana and also spirit energy simultaneously.
Both of their powers sky-rocketed surprising the big Vampire and the other two Vampires.
For them, it was basically a surreal scene where two Werewolves are doing fire magic which should be impossible. Each of the Supernatural races is connected to specific energy.
Moonlight for Werewolves, blood for Vampires, nature energy for Elves, and others.
These energies they are associated with are the foundation of their core power as Supernatural, it's inherited from the Origin as the base of their power.
So it's natural for them to view Adhara and Evelyn in absolute shock since Werewolves can only get their power from the moonlight energy, and the shaman is the only one that can harness that moonlight energy to cast spells.
