Lilith picked Artorius up to take him with her...just in case.

She then disappeared into the kitchen for a little bit to begin cooking. She had to really impress this stuck up snob if she wanted to get him to join them, the fact that he seemed to know magic made him invaluable. Even if he was a total tool, even if he would make her life much harder...having 2 members would be so much easier than having only one. 

She returned from the kitchen with the specialty dish in hand, piping hot, and even crustless like he had specified. Lilth then placed both the dish and Artorius down on the table before flashing her killer smile that she had been praised for before the Guild was a ghost town.

"So, what brings you to this neck of the woods, Drekven? If you don't mind me asking, that is."
