To believe in legends, one needs to accept there are powers and beings capable of things beyond the human imagination. God, who created all, gave different abilities to different beings, angels, gods, humans, creatures, and mixtures of each, all lived as one, some mortal, some immortal.
Many millennia ago, humans started worshipping immortals, making them more significant than they were meant to be. For that reason, they were no longer able to live as one. Mortals always wanted what the immortals had, and the immortals began using them as their minions to wage and fight in wars, not their own. God separated them all into realms; immortals could no longer live with humans but were still tasked to watch over them when called upon.
Unfortunately, if together longer than necessary, the mortal becomes confused. Are they experiencing reality or fantasy, dream or wake, real or unreal? This otherworldly confusion often leads to insanity and sometimes death.
Can the forbidden love of a mortal and a god overcome the chaos caused and stop insanity from taking over, or will death claim another victim?
