Final analysis (because I'm procrastinating):

The Drea rainforest, Moran, Colchetta, and the Chus-Cande island are on or near the same continent of Witherings, but the tribes have never met.

What the Colchettans call the River Oros, the Madakam call the River Ti-ain.

The mountains of the Four Tribes of the Wind stand between the jungles of Witherings and the Rune Desert.

The Ruins of Kimberton and the ruins visited by the Dryads are one and the same.

Seven years ago there was a great worldwide storm, more devastating for some than for others.

Nisa, Cyrus and Moria all speak English
Nisa and Moria speak Spanish
Cyrus and Moria speak Zulu and Arabic
Matin, Rosella and Moria speak "Common" (which for our purposes I think should be Cantran)
Therefore, Ila (and Ooko, when/if Xistina returns) is the only character that Moria can't translate for.

The gods Casper, Lutok and Ma-Ruk all have claim over being the Creator.

Everyone generally seems to agree that the Ruse are destructive to society in defense of Nature and are harbingers of disaster.

Edit: Still coming along. I have a small part finished, and I have a terrible habit of editing as I write. Hopefully in the next few days the first post (the hardest one of all!) will be up.

Edit 2: Halfway done, I think.
