Talk:Six Ancestors Great Seal/@comment-10534118-20160822054415/@comment-25707465-20160822183120

Also, for the ancestors, they were the one casting up the seal. In Alice's case, that was done by an exterior device.

One could also theorize about the trigger that can release the ancestors (excessive dark energy released due to an important number of monsters dying) is linked to the nature of the seal itself. since the ancestors and Alice are basically the source of all monsters =>Killing that much monsters is like killing an ancestor, aka "destroying" the seal's source.
