My thoughts on "Mount Targon" & "He Has Returned" teasers

I derived this from a post I made on Surrender @ 20's "He Has Returned" showcase. Here's the possibilities:

So, we have 2 missing spots in the Mount Targon page, much like PROJECT. This could mean quite a number of things.

• Aurelion Sol is one of the missing spots, and there's perhaps another champion that Riot is planning to release in the future, after AS, possibly in relation to.
• The teaser "He Has Returned" could be Riot making hints to Pantheon's rework, and AS will come out around the same time.
• The champions that are listed (Pantheon, Leona, Diana) all are from Mt. Targon, "a beacon to dreamers, madmen and questors of adventure". All of the listed champions also have something to do with the sky; Pantheon is the "celestial Aspect of War" - note, CELESTIAL. Diana is quite literally a lunatic, and Leona revolves around the sun (no, she's not a planet). Also note that Aurelion Sol roughly translates to Golden Sun. They're all a celestial embodiment.

Update: Take a very close look at the image, but make sure you look at it from a distance. https://4.bp.blogspot.com/-sNvIz7gjHfU/VtSg3enU7gI/AAAAAAAA4cI/iMTbl5ly9Ng/s1600/423423.jpg

By looking further, you can see what appears to be a dragon's hand - the claws can be seen under the galaxy itself, as if Aurelion Sol is holding the galaxy.
