I“ve previously linked to descriptions of, and video clips from, several crucial episodes of the original Galactica series that shed light on recent events in the current Galactica universe.
The videos have since been yanked from YouTube for copyright reasons, and the descriptions have lapsed into nonbeing along with their website, Sheba’s Galaxy; but the latter at least are still accessible via Internet Archive. There are also more recent descriptions at the Battlestar Wiki. Check ’em out to see what inspiration Ron Moore is drawing on for current storylines involving gods and chosen ones. (The Sheba pages have lost their dark background and will be more readable if you highlight them.)
