In the "Dragon Rider" movie, the capital of Oegesia wasn't extensively depicted, except for the protagonist's journey on his dragon mount to rescue Princess Oya. Furthermore, this "Dragon Rider" is no longer just a movie but a fully-fledged, realistic world with a capital city that is far grander and more majestic than depicted in the film. It might contain powers beyond the scope of the "Dragon Rider" storyline...
"This is exactly what I've been worried about. Logically, there shouldn't be anything left that could scare Imhotep.

He could surely escape, if not win... What kind of power is it that has made him feel fear?"
Zheng pondered aloud, jumping down from the pillar while communicating telepathically with Xuan through the silver metal piece.
