Re: Weekly Mini-Previews!
this is true but you can have her in the strat-map at beginning as a princess even if is married. Just delete her character-record, put her as a normall agent (character Dany, princess, female, age nn, x, y, portrait dany) and voilà, she will be in the family tree and in the map aswell. you can do this if you plan to make a Targaryen Faction; then you could have her in the strat-map as princess even if she is married, but it seems she will not be able to marry anybody... at least in my campaigns.
actually you could send her off-map and replace with another agent with the same name and portrait and then marry this "clone" to whoever you want to simulate a second marriage; and this could even be an event called up by scripting, so you kill the "original" in the family tree. The only thing, if you marry her to a family member of yours, there will be 2 Danaerys in the tree, a dead one (killed at the marriage by script) and the new one...
