Sebastian came to July's office room because he couldn't find Knox, since the man went out of the manor to meet with the people from the coven. They came to make a deal with them regarding territories.
The witches wanted to seek asylum from them because their kind was hard to be accepted by the other supernatural creatures. Almost all of them saw the witches as a threat, since they could use their spells to manipulate them.
Moreover, it was widely known how cunning and conniving a witch could be.
Therefore, neither packs of werewolves, vampires, dragon shifters, or any other supernatural creatures wanted to accept them, even though their number was not that high.
"July, we got a visitation," Sebastian reported this to July, while the woman was staring at the garden through the window in her office room. The light of the afternoon sun illuminated the room and herself. She looked beautiful, but somehow, she gave off this gloomy vibe from weeks ago.
