I've been reading the Lightbringer's book, the Earth Goddesses's book, and even the Glorantha Sourcebook, but I still struggle mildly with getting a grip on all its metaphysical splendour. Are there any real life religions from which some ideas are in Glorantha are taken? I believe Glorantha took some inspiration from proto-indo european religion, and therefore perhaps Vedic, and Sumerian/Akkadian gods are a good place to start?
Orlanth, however, makes me think that I should look closer at Greek Mythology and Norse Mythology, perhaps.
