The suit describes a fancy, lively banquet. It most likely takes place in Linsol, Pigeon due to the mention of Blossom of Abney, a champagne that the town is known for. The balcony at the banquet offers guests a view of the garden in the moonlight, and guests drank out of goblets until they were tipsy.
