He's getting ready for his revelation as [possibly messiah] King of Israel and Green Agenda "savior" of the world.

That sounds like a joke, but maybe it's not.

Charles is actually one of the WEF leaders and Earth worship climate change high priests. He has been working towards this for years and years. He probably wouldn't call himself a high priest, but as he is working towards forcing everyone to embrace his false pagan religion, he amounts to a "priest" of sorts.

Here you can see the statue created in Brazil some years back depicting Charles as the ecological "savior of the world." The picture doesn't show the base of the statue, but Charles is standing upon the "world" like a winged god:

There is some internet discussion that King Charles, as David's descendant, is expected to play a role in consecrating a newly built third temple in Jerusalem, the goal of which is sometime between now and 2030. In 2030, Charles will be 82. There are a lot of potential implications for Charles' role on the world stage. He has been waiting in the wings for 70 years.
