And so they can go in.
The throne room is made of the same sandstone as the rest of the palace, well lit with magic; it's a long, relatively narrow room, and the walls are hung with intricately carved wooden panels and backlit stained glass depicting various scenes - some appear to be battles, like one where a group of humanoids use sticks to menace what appears to be an orange-skinned humanoid, except that it has a swirl of magic in place of legs; others may depict more peaceful accomplishments, like one where a kneeling humanoid offers an implausibly large gemstone to a more elaborately dressed one. Guards with spears stand between the panels, almost like artwork themselves in their bronze chainmail and blue-trimmed white capes. A thick green carpet covers the center of the swirling mosaic of the floor, leading to the far end of the room, where a pair of steps separates the main area from the raised platform containing the throne, a bulky and relatively plain thing carved from a single piece of mottled translucent bright green stone, polished to a shine.
The man on the throne is more weathered-looking than the prince, but less so than Raafi, wearing a yellow silk outfit intricately embroidered in a rainbow of colors and holding a short bronze scepter with a red gem carved in the shape of a tongue of flame set into the top of it and a smaller blue gem hanging from a short chain at the bottom; a young woman with a familial resemblance to the king and the prince and wearing clothes only slightly less ornate than the king's stands demurely to the left of the throne.
Prince Maziar approaches the throne, stopping a few feet short of the steps, and bows, more deeply and for slightly longer than he did in the hall. "Your Majesty King Nawfal al-Kaprela al-Kamar, Princess Sahar, may I present the visitors from another world: Uamok, and her mates Iss, Zoi, Skon, and Kiv. Uamok, gentlemen, may I present His Majesty King Nawfal al-Kaprela al-Kamar and Her Highness Princess Sahar al-Kaprela al-Kamar."
"Welcome," says the king.
