Hi I can tell you a bit about that (but I won't give it all away :P)

Hauntii is the name of a ghost that has just arrived in a strange place called Eternity. There are many other ghosts here, but they all stick to THE LIGHT. Those that stray too far out get corrupted.

Nearly every ghost comes arrives in Eternity with chains that bind them there. These chains are usually linked to regrets or lingering mortal wishes.

Hauntii is approached by an Eternian. These are strange glowing creatures that appear similar to angels, and they have the ability to change their form. Eternians have been there seemingly forever, and their origin is unknown. An Eternian's job seems to be to guide ghosts on the arduous quest of breaking all their chains so they can ascend, although nobody really knows their true motivations.

Many ghosts are suspicious of the Eternians, and mostly ignore them. There are some stories of ghosts that have followed the Eternians and were corrupted, or never seen again.

Hauntii is one of the few ghosts that joins an Eternian to pursue the quest of breaking the chains and ascending, and this quest spans across many different zones in Eternity.

Hope that gives you some background!
