"You mean, you don't know? Thaczil was the original homeland of the Draconequines. It was a place protected by the most powerful of Draconequine magic. The spells were kept stable by the Tilabili, the greatest Draconequine sorcerers of the time: Ixen, Pab, Suaco, Edar, and Master Pliso. When I transformed into my current form and rampaged, I used my magic to send them away, to the farthest reaches of the world, and seal them in crystal. The protective spells around Thaczil faded, and the land became inhospitable. I found my way to Equestria, while the surviving Draconequines went into hiding."
*Discord pauses and takes a sip of his tea*
"I've recently completed a spell that only I can cast. It's a spell that can locate the unique energy signatures that the Tilabili give off. I'm preparing to set off to find them and free them."
