Alex had a decent life in the old world. A loving family, good friends and a bright future, almost everything that a guy could ask for. However, his life came crashing down around him, along with everyone else's on Day Zero; the day everything changed. The day Earth was in for a rude awakening that they weren't alone in the universe. The day that the first of the portals emerged and introduced humanity to the Other Worlds, and along came the unknown races. Life as Alex knew it was dead, and he must learn to survive in this newly ravaged battlefield he once called home. Throw in a witch-hunt and a quest, and one's got a perfect melody that sings chaos and death. Will Alex survive, will he adapt, or shall he perish among the remnants of the Old World?
