Jason walked to the Piano, the smooth Crimson Red stone felt perfect under his hands no imperfections, as he sat down and looked at the keys in front of him, he takes his time with it, some slow melody to something fast paced then he stops, he starts his better start with his favorite Song (Cruel Angel's Thesis - Neon Genesis Evangelion)

Has he plays Erika joins in with a voice that can melt frozen Hearts, with perfect pitch and translation, no word sound out of place.

a 3D map of his Dungeon started appearing on top the Piano. 

Jason opened his eyes as the song comes to an end, he saw the map "what is this map, is this my Dungeon?"

"Master You are in what's called the 'Overview' it allows you to control the Dungeon around you. now we need to do some set up."

[Dungeon Start up]

[Done]

[Dungeon layout in order]

Hallway, Room 1 (Edit), Hallway, Core Room

The mapped showed a normal one Hallway to the Room then, the Core Room "Okay looks Normal what does it mean Edit" Jason looked at Room 1 option

"Room 1 (Edit)?"

[Room 1 Edit options]

Theme: unchosen

"Theme what?" he asked no one

"Well what places did this 'undead' came from like started?" Erika asked showing that she did know fuck all about it, but this did make Jason think about it, Graveyard? Hospital? and others, so Theme is a setting of the Zombies like in the Movies cool.

"Choose Theme Hospital" Jason said with some hesitation as if he is unsure about how advanced this world was, to be surprised when a Modern Hospital took shape in the Room.

"Wait I know this place this is Mercy Hospital from Left 4 Dead" Jason exclaimed, he stepped away from the Piano and walked down into Room 1 and yes it looked like it straight from the Game with the Bodies on the floor, "Wait Erika, is it just me or are some of this Elves and Beast-kin, like really it seems odd for these Races to be in a Human Building that was never meant to see these Races, mmm Damn I have no Idea how my Disease would affect them? Shit will have to see when people come" Jason said the last part with some concern in his voice

Erika looked at Jason like he just said something Crazy, it sounded like he had never seen those Races and Humans have to deal with them all the time, in this world "Master what do you mean Have you never seen them before? others of your Race would have then."

"No one from my world would have seen them, my world has no other intelligent Race other than Human" Jason answered Erika

Erika started muttering to herself but Jason felt a Dark aura around her.

"mmm Trap time and Can put my first Stage of ZomBro 1 throughout my Dungeon to?" Jason asked and Erika Breaks her muttering

"Well it is already in the Dungeon its Airborne, it will be in the Air but will not leave our Home and annoyingly if someone is infected escapes from us the Disease will self-destroy to prevent them from making a Cure."

"Cure? wait how Advanced is this world?" Jason asked with some Confusion and Concern 

"umm Lord Death said 3 words to me and you would understand how advanced it is and what the world is like 'The Great War'"

"Piss, that's not good, can I use this world Tech for my traps?" Jason asked

"umm Maybe?" she replied but didn't understand the Question

"Can I Create traps the same way I can with my undead or Disease?" he asked he had a plan

"Oh Yes say Trap Creation Master" she Replied

"Good time to create landmines" Jason chuckled a bit "[Trap Creation]"

[Trap Creation]

"Can you use my memories for Creation right?" he asked

[Yes]

"Good look for any reference to Landmines in my memories"

[Calculating]

[Found]

[Done]

[Showing Results]

It showed 4 peasants walking down my Dungeon hallway, each spaced out with 8 meters from the First peasant to the Fourth one, when the First one stepped on the Landmine and it exploded, the effect in order was peasant 1 dead, peasant 2 lost limps from shrapnel, peasant 3 and 4 were fine and rushed forward trying to help the first 2, soon the peasant checking on peasant 1 then died when the Zombie bite his neck leaving the last peasant to die due to being frozen in fear. the Sim showed similar results where peasant 1 lives but bleeds out.

[Is this what you wanted]
[Yes]                            [No]

"Yes"

"Okay, can I hold a Landmine *Landmine appears in his hands* Well then." he walks over to some of the bodies and starts booby trapping them, and triggers and some different traps all meant to maul the target not kill them out right.

"Master what are you doing, I am little worried, Lord Death is laughing and the Lord is pleased with what you are doing, why not kill them out right?" Erika asked she sounded and looked scared "Master Lord Death only laughs when Death is playing with Mortal some oh" she stops herself then gives Jason a grin that doesn't belong on a living person, and said in a very cheerful tone with a hint of jealousy, "Master Lord Death always said that Death loved your darker side, your self-harming- UCH" She was cut off when Jason hit her with a Landmine

"YOU MAY NOT SPEAK AND DEATH YOU CAN FUCK YOURSELF, YOU, YOU HAVE NO IDEA THE STRESS I WENT THROUGH NEVER TREAT MY DARKER SIDE WITH YOUR ADORATION!" Jason dropped the Mine and ran back to his room and had a full mental breakdown, all the memories and trauma to try to be the best he could be and failed played in his mind, the self-harming he did sickened him, he loves the Piano in what seems like to him, a world that hated him.

Erika was confused about what happened didn't he like that darker side of him? she checked herself she was fine thou she was wacked in the face with the Mine she was fine, but still the shock of what happened that he tried to hurt her and even Lord Death was concerned and worried for his Mental state.
