Name is a bit pants, but I can kind of see where they're coming from with it since it follows the naming scheme Tomorrowland use for their main stage ("The book of wisdom", "The elixir of life", "The Reflection of Love", etc).
That said, the theming will look phenomenal if they manage to follow through on the concept art. I guess the stage set designers needed to let off some steam after the 2 years of the festival not happening.
