There are some characters that will develop multiple GIFTS. Functionally they are home in any of their Houses and are culturally viewed as a representation that all the Houses are to be united in their work in the world. Often they work as liaisons between the Houses. Not surprisingly, most often do not have time for any other organizations due to the tremendous responsibility expected of them.
Mechanically, GIFTS are obligations more than combat bonuses. A PC with two (or more) GIFTS will either find themselves occupied by duties related to those GIFTS or become a pariah viewed as greedy and self serving. While that may not always be the case, it is the cultural perception if the PC is unwilling to use those GIFTS in the manner they were intended. A player who rolls this should expect that many character actions over the character’s span will be absorbed by the role.
