Kaodi
Legend
Likewise, my youngest cousin, like me, is nuts about Greek & Norse mythology. Unlike me, though, he's never expressed an interest in TT gaming- he loves his console games.
Sub-Saharan African mythology is probably about as poorly circulated as could possibly be in North America, as far as I can tell.
I have at least heard something of Abrahamaic, Greek and Roman, Norse, Egyptian, Arabian, Sumerian, Zoroastrian, Hindu, Buddhist, Sikh, Shinto, Celtic, Aztec, Mayan, Native Canadian and Native American, Chinese, Maori, and Voodoo religious and mythological figures. And I suspect this list would be about the same for anyone with similar interests to ours.
The Dahomey, Igbo, and Yoruba pantheons might be suitable for translation into common D&D style... http://en.wikipedia.org/wiki/African_deities
