"Make way, make way!"
Never let it be said that Prince Blueblood didn't have a flair for spectacle and making an entrance. His showiness was often only restrained by an aristocratic sense of dignity. Some occasions, however, were sufficiently large as to overwhelm any hesitation, and this, well...
This occasion was as big as the Sphinx the Prince was currently riding on the back of through the cobbled streets of Canterlot.
"Behold, Citizens, the great Marvel of the Southern Desert Lands!"
The Sphinx's name was Niilavin, and Blue had encountered him while accompanying the Sultana of Saddle Arabia on an archaeological dig. Apparently, one of the old Pharaohs had enchanted the great desert cat, and subsequently petrified him upon his own death. By donning the amulet that had been used control Niil, Blueblood had broken the petrification spell, and become Niil's new master.
As the giant cat hadn't yet adjusted to the new norms of civilization quite yet ("No, we don't eat our enemies, we befriend them! Bad boy."), it had been decided that the safest thing to do would be to keep the enchantment going, while the Prince took Niil back to Equestria, more or less to housebreak him. Blueblood being Blueblood, however, he couldn't help but use the opportunity to show off his status.
So, taking a few souveniers home to dress himself similarly to a Pharoah of old, he now Paraded down the main streets and squares of Canterlot, showing of his new pet and his new bling to all and sundry. Faust only knew what the papers would make of this...
