Toz managed to calm down Asilean and, by threatening Dyra's life, made Yill explain what she had done to Taienra. Dyra was surprisingly cooperative during the process, probably due to Yill's lies being revealed.
Apparently, Starry Sky Whales were valuable outside the Mortal Realm as well. Starry Sky Whales, who had been hunted to near extinction, weren't faring much better in the Transcendent Realm. The only reason they hadn't died out was that people were preserving their lives in order to harvest as many starlight crystals as possible.
Although Yill didn't know if the forest on Taienra's back was beneficial or not, she knew that she was a Starry Sky Whale with incredible value. So, Yill had sent a message to the empire, after which a servant came and picked Taienra up.
Yill had been rewarded handsomely for her contribution, but she didn't know what happened to Taienra after that.
