Beale's duties include dirrecting the staff of the SaDiablo Hall, meeting and greeting guests at the door and bringing food and refreshments to both the family and their guests. Beale is often a central source of information and makes it his business to know what is going on in the family as well as the wearabouts of its members.
He has been known to offer his "unofficial" advice when asked and is often very wise in his responses.
In one instance a guest asks why a Warlord as powerful as Beale - who is descended to Red - would serve as a butler. In response the person questioned offers that there are few who would dare insult a butler that is most likely more powerful than them.
