Who? Hmmm, not sure if that applies in this case..."me", I guess, or Andrew May, as he has done the sculpting so far; and others, who haven't yet done any for it, but shall...
What? A sort of Fantasy India and South-East Asia with elements of Hindu and Buddhist Mythology; Thai, Burmese, Cambodian folklore; and Tibetan Sacred Art. Plus some inspiration from the Hari Siri komix.
When? It's set in a mythical "Time of Heroes" when gods and men walked together and fought demons and each other. Before the events in the Ramayana or the Mahabharata, or perhaps around the same time. Who knows? Time sorta tends to flow together in Myths anyway!
I think the Hari Ragat setting is just off the map to the east.
And then Andrew got me hooked on Tibetan sacred art and it sort of went from there!
