Sabrina continued to watch as Orion deciphered the runes in front of him.
She expected him to know a lot about runes but Sabrina wasn't expecting him to actually be a rune monarch.
Although, Sabrina had a hunch about this because of the things Lucille said about him, but she was still surprise to see what Orion was doing.
As a witch who had lived for more than a hundred years, Sabrina knew Salvatore was the last rune monarch in the world but even he wasn't really a true rune monarch because of how he stole that ability from Bjorn.
However, Orion didn't steal the ability from anyone, instead he earned it after studying magic circles and runes for years.
It was clear to see that Orion was also a true rune monarch just like Bjorn.
Sabrina was certain about this because of what she could see.
