Along the ruins of a forgotten kingdom, a harmless slime is minding its own business. It usually tends to itself, does not attack, and just bounces away from danger whenever possible.

One day, a group of greedy adventurers appeared, looting the ruins of its ancient treasures, wreaking havoc along the way, killing anything that moves for that sweet sweet experience points to level up.

Little did they know that this innocent looking slime is formed from the drop of blood of an archaic demon prince that walked these halls during the first age, and killing it would unleash a terrible nightmare...

-Special thanks to Ferch for the demo game. :)
