I heard from a reliable source that this guy is attempting to scam people with those two high level characters (439 EK & 456 MS). The same person also told me that the Knight has a deletion warning, and is not transferable.
Beware & Be Careful!
Note: This information was given to me. I have not been personally scammed by this user.
