Portalia is a world in a different dimension and home to creatures named Portalings.
Portalings could travel across dimensions via portals created by an ancient race known as Puros.

One day, the moon of Portalia turned gold. Innocent Portalings who looked upon the golden moon is infected by an incurable disease; the Midas Hunger.

Infected Portalings will have gold growing upon their body along with an insaturated hunger for more gold. This drove Portalings into madness. Soon, Portalings started attacking one another, bringing down the world of Portalia.

The ancient race of Puro came across a book on portals. It allowed travelling to a dimension known as C-32 which promises more gold to satiate the Midas Hunger. C-32 is also known as Earth.

Puro opened to portal and led the remaining good Portalings to Earth.

The portal energy eventually attracted the infected Portalings as well. Some of them even crossed to Earth.

Battle follows at portal crossings between Portalia and C-32. Good Portalings fight to defend while infected Portalings fight to come across.

Puro must now lead his band of good Portalings in this fight to defend both worlds.
In one of the battles, the book of portals was taken from Puro.
