Ang,
Crashing the party with Elves is an interesting complication!
Khandr is too much of a diplomat and has too much respect for the old ways to throw out Elves but he'll have to figure out a way to "invite" them to leave at some point in the evening so that the Borrim can plot and plan freely.
Meanwhile, Khandr will try to worm out what information he can from the visitors. Khandr will be discreet but he may give some indication that he thinks something "fishy" is going on at the Hall. This will not be said directly, but a bright Elf will undoubtedly get the meaning.....
