The Moondrop Saga

[A reboot of Coffee & Slime, three years later]
In the darkest parts of the peaceful world of Alta, an evil calamity that has been brewing for hundreds of years is finally set to unleash devastation and unspeakable horrors upon the land. It is at this time that our Hero is reincarnated into the world- as a slime! What can our Hero do to prevent this calamity from destroying the planet? Is there anything he can do? After all... he is just a mere slime.
If he does manage to do it though, it's bound to be incredibly epic.
