"Wow... What are these?... Oh my goodness... Isn't that... a blood-sucking tube? Oh... it's a filter, right? Oh my god!! It's a high-level filter that even has the ability to filter micro-level... Beaks? Tubes? Elemental separator? Mixer?..." Xara's face lit up with fascination as she looked around the room, her eyes wide and sparkling, marvelling at the sea of unfamiliar technology that seemed deeply connected to blood manipulation and alchemy.
Yes, this was the same forbidden place the previous Dragon Emperor had used for his vile and twisted deeds... creating unnatural, malformed children in his mad quest to extend his wicked lifespan.
