David, first real name: Ik-tong, from the tribe of Urduk on his first world, simultaneously traversed worlds and has ultimately trapped on "our" dimensional plane: the 'Author's Plane', where their tribes known as the 'God's Plane'.

He found himself on a consciousness of a boy named "David" where his current situation was found inside a Mental Institute. When he realized he can read, speak, and understand about his current situation; he realized he was labeled as "psychotic", though he didn't understand what it was at first; he instinctively knew he was called as someone possessed with demons. Or "crazy" as per the world's term.

Now, instead of brooding on his own situation, he decided to live while maintaining his composure and will to return to his tribe. Of course, to his loved ones.
