Treasure of the Rudras is another "lost" classic from the days of Super Nintendo. What is it about? Long ago, when the world was yet blanketed in chaos, it is said the Heavens gave
order to the chaos. That the Heavens bestowed great power upon the Earth
and brought unto it prosperity. Life on Earth was born. Those with
great intelligence, the holy race of the Danans. Controlling the seas, the
Mermaids. Proud, but arrogant, the Reptiles. And possessing
incredible strength, the Giants. However, they did not have the Heaven's
favor. And, in time, they disappeared. Then, the Heavens gave birth
once again. Life, 'tis said, flourished anew. Basically The story of Treasure of the Rudras is divided into three major scenarios, each with a different main character: the warrior Sion, the priestess Riza, and the archeologist 
Surlent. As the player enters new areas and accomplishes different
tasks, the human race's final 15 days slowly ebb away in a predetermined
day/night cycle. The player is free to play the scenarios in any order,
and may even leave one storyline to follow that of another character
for a time. The actions of the characters in one location and time may
have an effect on the others, as well, both in the general story and in
gameplay. I like to think of it as a more hardcore version of Final Fantasy VI. Not to mention the Mantra system is one of the game's greatest features.
