The Aviantese there were once disparate tribes, constantly warring with each other, but Armadyl united them.
Abbinah will feature heavily in an upcoming quest currently in the early design stages, entitled 'Rite of Passage'. It is confirmed that there are currently still a number of Aviantese left upon this world, and Armadyl is aware of them.
It should be noted that the floating citadels of Gielinor were not originally created by the Aviansie, only built upon because of the familarity they offered.
The origin of the name, Abbinah, came from Mod Raven researching Armadyl's origin. When he discovered that some players theorised that Armadyl's name might have come from the Seal of Solomon, Mod Raven began searching for words in the Kabbalah tradition. He found two words and merged them together into Abbinah, these were: Bina (meaning: celestial light, according to Mod Raven, as well as 'understanding' or 'contemplation' and called 'processed wisdom' on a psychological level) and Abidan (the idea of a wonderful, interesting world, which is actually quite a harsh world).
