Phase one, to study the historical data using documentary study. Phase two, to construct the plot of the opera using synthesized information starting from 1) general plot outlining the whole story, 2) specific plot in details with conflicts, 3) character portraying, and 4) constructing the libretto and narratives in the form of epistles.
