You've heard the legend of Mt. Ebott: "Those who travel there never return". You are the Eighth human to fall into the Underground. Down here, the unspoken rule is "Kill or Be Killed". Chances are, you'll be faced with numerous challenges that may lead to your inevitable doom, forced to fight powerful advecaries and monsters and to survive in a world unlike your own.

What will you do? Will you spare everyone you come across, or will you be a merciless killer who won't leave a single soul alone until you achieve your goal of escaping? Regardless of the perils that're bound to approach you, you feel something fill your soul. A burning passion to brave whatever dangers the Underground may throw at you. Whay you feel is...

Determination.
