I don't know what complement the table means so this may not seem too good...
Ok..
First off I shall sit at the head of the table facing away from thhe window
secondly to my right will be
Encantaire to her right will be
Grima Wortounge we know she likes the guy

Next to him will be
Rosey because... HMM.. so anyway next to her is of course
Sam since husband and wife must sit together next to him will be
Firefoot. at the opposite head of the table is
H-I cause hes very polite well mannered and I consider him a good friend.next to him is
Arwen and next to her
Aragorn and then
Child of the Seventh Age because she is also quite nice and polite and considered a good friend...the other seats are vacant so there is room for the food
