What if nightmares and dreams were people?

"From now on, any contact between Dreams and Nightmares... will be punished by death..." Announcement of the Powerful, in -180 756 987, End of the era of "Paradise", entry into the era of "The Hell"

For millennia, Dreams and Nightmares have coexisted in harmony, without war, without weapons, without blood... We called this era "Paradise" But one day, a Nightmare named Georges Malcketing used his powers on his concubine, killing her in excruciating pain... This caused the collapse of peace between the two species and the government decided to ban any meeting between dreams and nightmares. Separating them for eternity... Nightmares now appear as a symbol of destruction... of horror... And unfortunately, most allow themselves to be like this, condemned by the Powerful, governors and representatives of order.

The Dreams are separated from the Nightmares, the high schools cut in two by bewitched walls, preventing all contact. The same goes for stores. The residences are far away, to the North the Dreams and to the South the Nightmares...

Today, -60,478,987, or 120,278,000 years later. You are in the forest reading a book when suddenly you hear a noise behind a tree, and see the shadow of a Nightmare... Yeonjun
