Lucifer means Lightbringer (Bloodstone Compendium 6)

Venus-based mythology is perhaps some of the most important world mythology to know if you want to understand A Song of Ice and Fire. George has drawn upon it in creating the Night's Watch, House Dayne and the Sword Dawn, and of course, Lightbringer, as well as a few other things. 'Lucifer' is the Latin word for the planet Venus when it appears as the Morningstar - the bright star which appears in the east just before sunrise and heralds the break of day. The word Lucifer also translates to "light-bringer," "dawn-bringer," and "son of the morning." Calling Azor Ahai's famous sword "Lightbringer" directly equates it with Venus, and indeed, heralding the end of the Long Night is what Lightbringer is supposed to do.  But due to interesting celestial mechanics, Venus also takes a turn as the Evenstar - the bright star that appears in the west at sunset and heralds the nightfall. This is what our theorizing has told us about Azor Ahai - he's actually the dude who brought on the Long Night. In an interesting parallel, the Bible names both Jesus and Lucifer as the Morningstar.  All of this mythology is expressing the dual nature of the planet Venus, and that's what we'll explore in this podcast.As usual, the matching text is available on lucifermeanslightbringer.com
