That 'archetypal appearance' description is inaccurate. I mentioned it in your blog, so I won't go into detail about it here.

One thing I have noticed, though, his owl face could simply be an implicit reference to his supposed wisdom. In animistic cultures, the owl is a totem or spirit animal which symbolizes wisdom, seeing past illusions, intuition, and in some other cultures, a harbinger of death.

So that form could just be Lille esteeming himself highly, by implicating that he's very wise (enlightened), and he's come to 'purge the world of darkness with his light', seeing as he's on a rant about being a messenger of God and whatnot.
