The hint says "the Oracle facing North"

Catherine said: "Did you notice the hint of the Oracle facing North? take a look at the platform. That's a pretty strong hint as to some of whats coming very shortly!"

I visited Roo, and took some snapshots. I opened mini map and tried to figure out where is the north? I walked to the north and arrived at a desolate place that looks like this.

I moved my camera higher, and found that the Oracle is actually facing north east of the sim. I told myself, "north" is actually north east of the sim because "the Oracle facing North". Noticed that the archway entrance is located at north .

Then, "take a look at the platform". The Oracle is facing north, and at north, south, east, west, each direction has a symbol on it. 

Dryads are the Watchers of North (Sula), South (Troo), East (Myrr) and West (Azra), I think somehow they are related to these four symbols. 

At the archway, there are 5 symbols on it too. They look very similar. That one on bottom left is exactly the same like one of the symbol on the pre-order necklace.

I walked out and continued heading north. Didn't see anything extraordinary, but there's a meeroo statue.

I looked from the outside of the front entrance. I can see the Dryad platform. Still nothing extraordinary.

I moved my camera going up a bit higher. There is a symbol in the sky. See the symbol that I circled it, another symbol that is on the pre-order necklace.

A closer look of the meeroo statue. Very beautiful, but does it related to the puzzle that is coming soon? And what are the blue dots behind there? Well, maybe I think too much. That probably just one of the decoration on the sim.

I continued to walk. Then I see the pyramid. I am not sure, but I think it has nothing to do with the puzzle.

Seems that I already came to the end of north. When I cam around, I saw a chair. Oh, very pretty. Is it official? Is it for sale? I don't know.

 End of my journey in Roo. Time to rest~

EDITED: I DON'T KNOW WHY THE ORACLE IS FACING NORTH. AND NOTHING SEEMS TO BE RELATED TO THE PUZZLE. BUT I DID GET THE MESSAGE AND THE GIFT AT THE END. THE GIFT PICTURE IS HERE.
