Is the Darkin the weapon or the horned creature that wields it?
So, there's something I still don't understand about the Darkin. I thought I knew the answer, but seeing the sword with a beating heart in the Aatrox trailer has confused me again.
If a Darkin fully takes over its host, does its soul get transferred from the weapon to the body of the host, and thereby actually become the red, horned creature that wields it, or does its soul remain in the weapon, from where it continues to puppeteer the red, horned creature, who is just the host body mutated by the effects of the weapon?
