Light Beings Lost On Earth

What if you accidentally climbed through a portal into a different world? Elan's world falls apart when his twin brother Uani is snatched from right in front of his eyes by winged creatures. Uani disappears into the uncharted subterranean passages of the planet Hathalia. Summoning all his courage, Elan joins the warriors to travel down into Hathalia's depths to find Uani and ends up crawling up through a portal into Yellowstone National Park. Eleven and alone, alien Elan needs to find a way to survive on Earth as he starts the daunting task of finding his twin brother. Elan's search for his twin brother leads him into a fight to save the Earth from other parasitic alien invaders. Will Elan find his brother? Will he succeed in keeping the humans from the malevolent alien invaders in time? If given a chance, will Elan stay and fight for a planet and people that aren't his own, or will he use the portal to take him to his home planet instead?
