breaking off (one's engagement)

Exploration Stage: Heirs' Villa
From: Eli Montague
Description: If the portrait was just missing, it could be explained by thinking it was accidentally peeled off and lost... but I found a torn wedding invitation in the Luxmore family archives. Odd, isn't it? Let's look for it.
Completed: There must be some reason why there is a torn wedding invitation among the documents. The writing is faded and unreadable, but it could be that someone in the Luxmore family was expelled for refusing an arranged marriage.
