At last, i learnt that a supplement named "Arrows of Indra" exists.
While i don't personally agree in playing in such a "mythological" setting, and i have more than a few doubts about the content of this supplement, (treatment of the Yogis and their siddhis for instance, it irritates me in much the same way as if someone put in a game the possibility of Christian resurrection treated just as a mere magical spell (D&D)- in much the same way i dislike when i see that Siddhis are treated as a joke as well, see here.)-
Anyway, i decided to share some vid links which may or may not be of some use (to induce some ideas) in those fellow gamers who are not as hesitant as me in adventuring in that very setting (watch this video especially from minute 2.00 on).
Check also this book, that i read today at my local library.
