Undeterred

After waking up injuired onto a patch of hallucinogenic flowers, the injured human's mind is accompanied by a shadowey figure simply labeled The Dark Passenger; a resemblance and embodied entity of the previous incarnation's sins who only appears when the human is in mortal danger.
A peace treaty with the Humans, a thought disregarded by The Royal Guards, whose Queen vowed vengence against the humans for sealing Monsters underground, for thousands of years. The first and only rebellious group, Voxel Reach was banded by Monsters who are willing to die to escape the Underground and live among humans peacefully. As disagreements between two parties of Monsters erupts into deterrence warfare, Death's sythe unsheathed as negotiations become more and more victims to disagreements.
The Underground lives in sinister times for an imminent Civil War is ready to erupt at the second.
Frisk, will she give into the Dark Passenger, will she bring peace to the monsters, or find a way out of here?
