Lord of the Hidden Layer
Oh look what you went and empowered, the thread is going to live - again - of its own accord !And, as I stated in this thread, world building, outside of simply setting the scene, is, IMO, a complete waste of time and largely a pile of DM wankery. Set the scene, and get to the point. Worry about the entire royal family's family tree going back three generations is pointless. You have the king, you have the queen, you have a kid or three as needed by the plot and off you go. Done and done.

I've found that as DM I can get lost in the weeds and my players won't mount an expedition to find me and bring me back. I'm a lore-o-holic.
But they did like when I introduced the Griffon Cavalry of Waterdeep into my Tiamat campaign and sent them on a quest to find some griffon-riding gear.
Had the campaign continued, their patron was going to make another cameo appearance riding a griffon (based on friend's experience learning to ride a horse).
For the final chapter of the book, they would be flown to Tiamat's Lair ... via griffon.
