I'm Andrew First, Leader of the Architects Clan. I founded the City of Sangis, and it's grown so much that it's now become a nation of its own. Together with my friends, I was able to build a place of safety in this post-apocalyptic world. We've been attacked by zombies, monsters, and people—but we've managed to fight off all of them. But it seems the Dark Sphere doesn't want to leave us in peace. It's announced that there's going to be a LEVEL RUN!
