(for any G-fans, Xenilla is the kaiju you may know as Spacegodzilla. I changed the name because I got quirked about typing it repeatedly and am writing the story so it can at least be understood by just an MLP or just a G-fan; and thought it get very confusing that one character's name was just another character's name with an adjective. Also... don't pretend it's the most imaginative name Toho has every made)

Long ago, the Father of all Monsters gave birth to many creatures. Some monstrous, others wonderous. Hidden away for hundreds of years by the ponies that proceeded them, these creatures have largely faded into myth in the eyes of most. Twilight Sparkle is far from most, given over the past few years she's seen things that would drive most ponies mad.

Looking at you Discord.

So, when rumors start circulating of an ancient temple in the Guoxia Province, one guarded by an ancient beast she is naturally intrigued...

Long Live the Queen...
