I love the detailed history! I sort of make my stuff up as I go for the most part lol! So I'm thinking maybe rumors of Archer would have gotten around the court that Eve was in, as told by the succubus who changed him (her name shall be Myra) for she boasted of cursing and changing the gentlemanly knight but was also incredibly bitter about having been spurned by a human. Her description is of long dark/black hair and black eyes and pale skin. Archer has thus far kept himself remote from the fae community and courts although over time he has appeared to mingle with a few other Supernaturals, taking a keen interest in vampires due to his own curse.

If you want to have her know of Archer then that could always be a starting point - plus since Eve was higher up on the hierarchy he might seek her out to see if she could help in the search of the artifact (if Sharpie agrees xD) which could be the starting point of their initial contact
