"I hadn't heard of this name before you mentioned it," the Tree of Knowledge replied.
The Tree of Knowledge possesses thousands of years of accumulated memories and knowledge, but that doesn't mean it knows everything.
If the Bone Sovereign never appeared on the Queldorei Continent, nor did it contact the Elf Clan, it's normal for the Tree of Knowledge not to know.
The reason Lu Heng wanted to ask about the Bone Sovereign was that, during his time in the Wugu Blue Cave, he speculated that the Bone Sovereign was hiding from a powerful entity or some civilization.
In other words, if the origin of the Bone Sovereign is known, perhaps the entity or civilization it fears can be found.
If the feared entity can be found, this crisis might become much simpler.
However, since even the Tree of Knowledge doesn't know, there's nothing that can be done.
Subsequently, Lu Heng expressed his desire to talk to the Tree of Knowledge alone.
Everyone else then withdrew.
