Finally, you found what you were looking for in the encyclopedia. The monster seemed to fit what Dean had said earlier. You hadn't heard of it yet, but it didn't seem to be too common anyways.

*****************************************************************

The Edimmu

The Edimmu (sometimes known as Ekimmu) is a type of spirit that has escaped the underworld either by their own power or by being summoned. The broader term for this being is Utukku, but the ones that turn evil and are an actual danger are called Edimmu's. The beings are documented by Sumerian religions religious groups which were heavily influenced by Mesopotamian mythology.

They are known to cause illness and inspire criminal behavior in those who either disrespected taboos (such as eating ox meat, in the culture where they're from) or those who have disrespected the dead. Also they seem to favor the young and drain their victims of all life (and in some cases blood). Sometimes they are described as being the ghosts of those who weren't buried properly.

The Men of Letters have not encountered an Edimmu yet and therefore don't know of any method of slaying one.

“Of course,” you sighed and pinched the bridge of your nose. How were you going to tell Dean that you knew what they were hunting, but you couldn't tell him how to kill it? He wouldn't like it and you didn't either because it still meant that there was a potential risk for people to get hurt and killed. Whenever you didn't know what to do and how to gain the missing information you would usually ask Castiel since the angel always either seemed to know the answer or knew someone who could answer you.

Calling him was impossible, however, since he was currently still in the mountains and reaching him via phone was a matter of luck. Said luck didn't seem to be on your side what so ever these last few days.

'I mean, I could ask Lucifer, couldn't I?' you thought to yourself but quickly brushed it out of your mind. As if the angel would answer you anyways.

'Maybe I could try summoning Crowley?' But shortly after coming up with this idea you remembered how badly your last experience with the demon had gone. The King of Hell seemed to like you more than the brothers but his constant sexual innuendos were even more annoying than Lucifer's smug behavior.

'Well, it won't hurt me to at least try, right?'

And so you rushed to the library once again, hoping he'd be there somewhere. Your hopes where destroyed, however, when you couldn't spot the man anywhere upon your arrival.

“Lucifer?” you asked, thinking that he may be somewhere behind a shelf where you couldn't see him but you got no answer.

Alarmed by this you slowly laid down the encyclopedia on one of the tables and started to check everywhere with your pocketknife raised out of habit. But still, after you had declared the entire library empty the sense of danger wasn't gone.

'Well there is still a celestial being in close proximity here somewhere' you thought as you tried to explain your fear to yourself.

You still needed to find him and so you checked the closest rooms but to no avail. Then you went to the kitchen to check there and opened the door.

It seemed empty as well at first but then you suddenly heard a coughing sound from behind the counter. Raising your knife again you circled the counter facing it and keeping as much distance as you could.

Sitting there sluggishly with his back braced against the counter and his head slouching to the side slightly was Lucifer. Just as you had expected he didn't seem to enjoy your presence. Or at least he wasn't acknowledging you since he was gulping down what seemed like his fourth bottle of water with the empty jugs lying next to him.

“What are you doing?” you questioned his behavior. He gazed up at you and now you could see his flushed cheeks and glossy eyes. There were even red splotches on his neck and ears and he seemed to be sweating profusely. However, he promptly ignored you again and continued to drink his water.

“We should get you some help.” you said more to yourself than to Lucifer but he promptly answered you anyway.

“Yeah sure, let's call a doctor and be like” he stopped and cleared his throat only to continue talking in a much higher pitched voice, clearly imitating yours “Um sorry, this angel here is sick. Can you prescribe him some celestial medicine? His grace can't do the job anymore because of his father's idiocy.”

Instead of taking offense you laughed a little at his remarks since you thought it to be quite amusing. The fallen angel seemed to be taken aback by this and stared at you for a moment before taking another sip of water.

“But seriously, though, I think you're dehydrating and overheating.” you stated shortly after.

“And what do you suggest I do about that, Doctor (Y/N)?” he tried to mock your concern again but this time you deliberately ignored it.

“Well, we need you to change clothes, take a shower and then drink some broth before laying down in a bed and sleep under some warm covers. That's how humans treat your kind of symptoms. First of all, however, I need your help and it's urgent.”

“What's the matter? Didn't find your magical beast in the big book?” he snickered and you noticed that he seemed to be quite drowsy and if you didn't know any better you would have thought he was drunk.

“I found it. It's called an Edimmu but it doesn't say how to kill it. I thought maybe you know something.”

“I do.” Lucifer grinned at you and sipped on his water bottle.

“Well, then would you care to enlighten me?”

“Maybe,” he snickered again. His behavior was mimicking that of a drunk human and you remembered that sometimes really ill people would act similar to him.

“Lucifer, how do Dean and Sam kill the Edimmu?” you asked directly this time so he couldn't avoid your question.

“They don't.” Another short answer followed by a grin and a laugh. This was really getting on your nerves but you attempted not to show it since that would probably just spur him on.

“Then what can they do to eliminate this creature?”

“One can't kill an Ekimmu but one must eliminate the Ekimmu's cause.”

“Are you fucking speaking in riddles with me now, Lucifer?” you shouted, your anger rising.

The ill man in front of you was startled by this and quickly covered his ears with his hands before glaring at you.

“Shut up. Don't be so loud my ears hurt enough as it is.”

But you couldn't bring yourself to care about this right now.

“Boo fucking hoo, Lucifer. Now you have an ear infection as well? Well, guess what? I don't fucking care if big scary Lucifer is having a little grace crisis. Humans get sick all the fucking time and we're not that big of a crybaby! Now – for the love of your father which I know you haven't experienced a lot – how does one eliminate an Ekimmu exactly?”

The angel was fuming with rage the moment you started shouting at him again. He stood up and even though he was shaky on his legs he still had that cold aura of absolute dominance surrounding him as he was towering over you.

“Don't ever think of mentioning my father like that again and don't you dare to compare me to your kind at all!” he hissed before turning around to steady himself by grasping the counter.

“LEAVE!” he screamed when you didn't move. His voice was raspy and for a moment you thought about how much it must hurt him to raise his voice like that. The concern quickly changed into anger however and you stomped out of the kitchen slamming the door when you exited.

Mumbling some swear words that you probably shouldn't use, you sat down in the library and opened the encyclopedia once more. Lucifer had said that Edimmus were killed by eliminating their cause, right? You reread the entry once more and decided to call Dean to tell him what you had found.

“Yes, hello?” he answered the phone sounding like you had just woken him up from a deep slumber.

“So Dean get this.” you got straight to the point. “I think I know how to help you with that monster.”

“Okay shoot,” Dean responded.

“It's an Edimmu or Ekimmu. They're like ghosts, well you know actually they're more like -”

“It's okay (Y/N). I'm sure they're terribly interesting creatures. So how do I kill it?”

“You need to eradicate its cause. Meaning, you either go and find the person that summoned it which would most likely be some sort of priest or you have to find whoever disrespected the dead or taboos or wasn't buried properly.”

“That's a whole list of potential causes then. Thanks anyways (Y/N)! How's everything going?”

You sighed and answered reluctantly “It's alright, Dean-o. Just concentrate on killing that thing and then bringing Cas home alright?”

“Sure thing, sweetheart,” he said and you hang up.

Shortly after you placed the heavy book back where it belonged and stretched your neck and arms a little bit thinking about what you were going to do with the sick angel you were supposed to take care of but always ended up fighting with.

'Maybe I should try and understand him a little better?' you thought searching for the fault in your behavior. 'I haven't been exactly nice myself now have I?'

You were ripped out of your thoughts when a loud crashing noise followed by glass breaking could be heard from the kitchen.

Concerned for your kitchen appliances you rushed to the room only to find half of the counter top empty like someone had brushed their arm over it.

Still, this did nothing to explain the other sound and you quickly looked around to find the cause. And said cause was quite easy to be found since it was about 6'3'' tall and currently lying on the kitchen floor in midst of broken glass and shattered kitchen ware completely unconscious once again.

Somehow you really did feel responsible for him. It was Chucks intend after all. You didn't know why and you were sure that you weren't going to find out the reason behind his actions by doing nothing and not playing along.
