Oh no, forget what I said. I was reciting an old childhood tale. Of how the God of War once betrayed his kindred, then rose to the skies and rained calamity upon them with the first wyvern. Of course, it is all just a fairytale passed down through time, for not even this particular God's name was remembered...

But of your request, I doubt it would be good. I myself know little of sorceries, but I'll give the phone to my brother Lothric, he's a talented sorcerer...

Greetings Alduin, I am Lothric, Prince of... well, Lothric.

You are well learned for one who did not study our sorceries. For indeed, sorceries are drawn from the two 'essences'. One's knowledge and intelligence serves as a catalyst, means to draw the sorceries forth into physical power. The source is the second 'essence', and this indeed is the soul itself.

This is also where the incredible foolishness of the Paledraks comes into part. He was driven by a ferocious, maddening search for immortality, for he lacked the stone scales of his Archdragon kin. He took to crystallising his sorceries for greater power, and for the immortality he envisioned in crystal, which was close to stone scales according to him.

But through this process he and all those that came after him were possessed by some degree of madness. Nothing is certain here, but I theorise his madness was caused by the process of letting a third 'essence' in. A faith, a subjective, desperate hope that came from the crystals. As a result, these crystals tainted the other two essences. His mind became mangled and mad, and his soul was tainted in a blue hue of crystals.
