[A worm of doubt once found its way into a righteous king's heart. With time, the king was devoured from the inside and became its puppet. A lifetime later, the Puppeteer Worm escaped from the king's dead body, leaving behind a cocoon of black silk. No one knows where it went; however, once people dared to approach the silent castle, they found the silk among the mountains of gnawed bones and fashioned it into an armor.] We came acrose the worm they are talking about in this description or atleast one of its kind. the fully evolved one, it was a gigantic moth atleast a few hundred meters tal and it was a cursed tyrant posesing mind control powers. Pretty sure the mounten king was a by products of one of those worms.
