After Illidan and Mannoroth returned, they presented the Dragon Soul to Roy.
Roy played with this divine artifact. The Dragon Soul was about the size of a millstone, and it looked like a pendant on a necklace, but the huge gem in it was like a mirror, with abundant energy sealed in it.
Knowing the history of Azeroth, Roy knew very well that when this artifact fell into the hands of the Burning Legion, it meant that the explosion of the Well of Eternity would not be far away. At that time, even his power projection might be forcibly sucked back into the portal.
In that case, it's time to prepare to take back what belongs to me…
With this thought in mind, Roy threw the Dragon Soul to Mannoroth and got him to strengthen the portal. Then he said to Illidan, "You did well. When Lord Sargeras comes, he will give you the reward you deserve."
