Karyk had left a shadow to keep an eye on the young time lord to make sure that he didn't lose him. However, even he hadn't expected the time lord to try to escape from this world in such haste.
By the time he received the information from his shadow and rushed towards the portal, it was already too late. He could see the traces of the time lord and his followers, which disappeared near the portal.
The Aetherian Beast saw Karyk and transformed into his humanoid form as well.
"Aren't you the new guy who joined us? I heard a lot about you," the Aetherian Beast said, revealing a pleasant surprise.
"I was quite frustrated that I wasn't able to see our new family member since I had to guard this place. It's good that I finally got to see you, young one." He approached Karyk and placed a hand on his shoulder. "I also wanted to thank you for helping in retrieving our ancestor's body."
