the History of " Oa "

post #1986, so you don't forget

Pronounced Oh - ah  ( more or less )

Historically, my first remembrance of  ' Oa ' is in the Douglas Adams novel " the Long Dark TeaTime of the Soul ". tLDTotS, is a continuation of the Dirk Gently series.
DG is an holistic detective. DG believes in the interconnectedness of everything. If you're thinking like ' a butterfly flaps its wings in the Amazon and a storm will break out in the MidWest ' - you're barely luke warm.
DG would say ' I may not get to where I wanted to go but surely I will get to where I'm meant to be '. To wit, DG follows a car on the basis that the driver appears to know where he/ she is going. And will undoubtedly get DG where ' he was meant to be '
Well, in searching for a god who is running amok in London, DG finds an alternative plane of existence in St Pancreas Stn, London.
He, in fact, finds Valhalla.
And while seeking answers to his many questions discovers that using the sound ' Oa ' that he can get a character in the alternative plane to carry on a monologue, loaded w/ information. 
Viking : " and Thor has not appeared again "
DG :       " Oa "
Viking: " the penalty will be dire "
DG :         Oa "
and so on
Not information that DG wanted but information that he needed.
Oa

And flash forward to 2014, and Oa is a planet created by the Immortals ( error ) Guardians as a home for the Green Lantern corps. And naturally, Hal Jordan ( Earth's Green Lantern ) travels there to become a full fledged GL.
