Generally, yes. All Archons will have the ability to appear however they wish at any given time, especially to the humans. That being said, they must choose a standard form that they take when in the white void. This appearance will be their normal default appearance, and the only rule i am putting on that, is it has to be relatively realistic, in size especially. Sky-scraper-sized squid monsters wont be allowed as default appearances, however, they are free to shapeshift or cast illusions to look like them in the main world or their own created world if they want to.
