I find the references in the Rulebook to the effect that all PC:s are part of the RT Dynasty rather obscure. A brief text explaining the usual contractual relationship between the RT and his retainers would have been useful. Because I assume that this is what it means: Other PC:s are junior partners or senior retainers in/of the Dynasty. Some may have actual family ties with the RT, others (such as the navigator) certainly does not. The dynasty is basically a corporation formed around a family lineage. Did I get this right?
If so, it would be cool to explore different forms of associations. Some Dynasties may tie their key staff to them through actual adoptions, other may be partnerships, others again may be more feudal with oaths of fealty and vassalship.
