Every Phantom strong enough knew that at some point, the Citadel and the entire world would be destroyed once every 250 years during the World Wipe.
Also, all Phantoms understood that they had to thank Queen Elisa for giving them the opportunity to survive the World Wipe. Well, only if they were strong enough, but weak Phantoms did not know this terrible secret about their world.
However, even though Queen Elisa held a specific and crucial position in humanity, she was not a unique being. She was still a human and a Phantom, a very powerful one.
Her ability to create a protective barrier was not one of a kind, well. Every Lord was capable of doing the same, and therefore every Second Rank Phantom.
Unfortunately, Queen Elisa could not join forces with Phantoms such as Damien and Frida to expand her barrier and cover the entire Citadel. Each barrier worked separately, so the area covered depended on the power of one particular Phantom or Lord.
