Time-skipped continuation of Itinerant Kingdom, picking up in MLP Season 5 / The Silver Stars chapter 64.

The fate of Equestria is held in the hooves of five terrifying beasts: creatures with magical horns, powerful wings, and in one cases a pair of deadly fangs. Princesses. Now Daniel Holden, the Itinerant King, will face these dangerous beings, not in the relative safety of mortal combat, but in the most dangerous of contests imaginable: diplomacy!

If everything goes well, his subjects will be able to emerge from the shadows, wear their allegiance openly, trade for rare and restricted materials to enable their more experimental industries, and have an impact on the world beyond the personal. They will also have the freedom to bring their combat potential to bear to protect ponies and others from threats they dare not engage before, for simple fear of being discovered.

And if all goes poorly? If they thought hiding in the shadows was hard, just wait until the Sun itself is their enemy.
