Although marriages within your clan between daughters and retainers is possible, the female members of your family are also useful diplomatic tools when dealing with other clans. The offering of an unmarried daughter by one clan to another in order to seal good relations between the two can greatly strengthen a diplomatic relationship and produce heirs to the leadership of the husband's clan. When a daughter is offered and accepted she is immediately removed from your family tree. Only clans with a neutral diplomatic relationship or better can inter-marry, and of course other clans may disapprove of the match, negatively affecting your relations with them. If marriage is offered to you when you have no suitable family members available, another clan member may be accepted as a suitor.
