How Do You Tell Stories?

Usually, I come up with a scenario and play it out. However, if events happen in the game that wasn't planned an example Morgyn and L getting married. Simeon and L having kids and getting married. I roll with it and redo the focus of the story. In a recent story, L and Morgyn got married. I was originally going to add in one of my sorceresses and her wife who is a spellcaster once they had kids. But my sim married Simeon and their kids will be the ones that will be hooked up with Morgyn and L's kids. If Simeon and Morgyn end up together in a game I'll have a family in mind to hook them up with. I have a feeling it will happen one day. I could always turn Simeon into a sorcerer of White Magic and have him use a creation spell on Morgyn since a Sage can be a Sorcerer without losing their status as a Sage. However, that would kind of be a bit of a cheat. I want to see how each of the combinations of Sages' children will end up as and compare each line after about 10 generations. I am at gen 5 with Simeon and L's line.
