Powerful mages constructed portals, with the goal of discovering other worlds. Successfully they managed to travel to a world where magic barely existed. Thousands of years after leaving that world behind, the portals lit up once more. But it was from the other side. Now the world of magic has to deal with forces they've never encountered before.  The Elven kingdom of Vatur struggles to fortify the portal gates in hopes of preventing further invasions from breaching into their world. Immune to magic and with devastatingly powerful technology, the enemy proves to be a force that threatens to trample the entire Kingdom and the lands beyond, in search of something yet unknown.
