The Ethereans Dark Genesis

Exploration holds no limits for the Ethereans.
As immortal explorers and advanced beings of light, the Ethereans use projection technology to create anything, become anything they can imagine, exploring worlds amid both light and dark realms. As light-bringers, the Ethereans find the lost. They never lose their way... until now.
To know the unknowable.
The most honored Etherean The Great Explorer promises to show his fellow explorers a realm where they may know the unknowable, think the unthinkable, and make possible the impossible. Only then, may they call themselves ultimate explorers. Then the unimaginable happens.
Lost in a strange new realm.
They lose contact with The Great Explorer after he enters a strange, new virtual realm he created using an unstable element known as energy. For the first time, light and dark coexist in a simulation of true reality. And the impartial administrator of his new realm the Overseer is using his access privileges to recruit players in his new game of gods and mortals.
They launch a rescue mission.
The Ethereans launch a rescue mission to find him and the others lost to this mysterious new realm. Captain Kestrel and his intrepid crew must find their kindred before the obstacles between them grow insurmountable. But like their hero, will they suffer the same fate?
Will they be lost forever?
