Per 
Special Containment Procedures:
SCP-7150 is to be kept in a soundproof containment chamber; within that chamber there should be a bedroom, a living room, a kitchen and a toilet. The kitchen must have cupboard, a dishwasher, a washing machine, a kettle, a toaster and a microwave. The living room is to have a sofa and a TV and the bedroom should have a bed and a Chester draws. The toilet is to have a toilet, a sink, a shower and a bath. The chamber is to be accessible for tests and there should be a microphone and a speaker for communication with SCP-7150. There is to be a supply hatch in the kitchen for his daily delivery of food and washing items.
SCP-7150-1 is to be kept in a sealed, soundproof safe in a separate room to SCP-7150 and it is only to be taken out by authority of the 05 counsel for testing purposes only. In any instance of SCP-7150-2 the subject is to be kept in a soundproof glass cage for 2 weeks of testing. After 2 weeks of being held in containment the subject is to be terminated.
Temporary Containment Procedures:
SCP-7150 is to be treated like a D-class personal and he is to be kept in chins at all times when in transport but he is to be kept away from any other personal. SCP-7150 is not to be given access to anywhere near SCP-7150-1's safe. This is to happen until proper containment can be reached.
Description:
SCP-7150 is a 3ft high humanoid entity that resembles the figure of a medieval dwarf. SCP-7150 can communicate fluently in old English and Nordic, as well as French. SCP-7150 will not act hostile towards anyone unless SCP-7150 has SCP-7150-1, in which case SCP-7150 will go on a rampage brainwashing anyone he sees with his soothing banjo tune. SCP-7150 acts like a normal person but will do anything to get hold of SCP-7150-1.
SCP-7150-1 resembles a classic medieval banjo made of an unknown material now known by facility personal as [REDACTED]. [REDACTED] seems to have traces of magnesium and copper and it seems to be indestructible. The Strings of SCP-7150 are made from a mix of [REDACTED] and animal hair.
Discovery:
The initial containment of SCP-7150 took many attempts due to the fact SCP-7150 brainwashed many [REDACTED] soldiers. Eventually Dr. [REDACTED] managed to have an interview with SCP-7150 when NTF where finally able to take away SCP-7150-1 from SCP-7150.
<Begin Log>
SCP-7150:
Bonjour comment allez-vous aujourd'hui?
Dr. [REDACTED]:
Is that French?
Can we get a translator?
SCP-7150:
Aaah, the kings English, there is no need for you to have a translator, I speak it fine.
Dr. [REDACTED]:
SCP-7150, I am Dr. [REDACTED]. I am here to make sure you know everything you need to know.
SCP-7150:
Good, I was hoping someone would come and explain to me why I'm here.
Dr.[REDACTED]:
You are here in the foundation because there is no need for the public to have any danger from you, and there is no need for there to be another threat to humanity.
SCP-7150:
Me, a danger? Oh Dr. [REDACTED] you do make me laugh. I would do nothing to this world that isn't reasonable. Anyway lets get on with what I need to know about this place.
Dr. [REDACTED]:
Righto, First, this is your new home. every day through the kitchen hatch you will be delivered supplies by a D-class personal.These supplies will include food and washing detergent.
SCP-7150:
What about a drink?
Dr. [REDACTED]:
Your taps are linked in with clean running water, so you can have as much as you want.
SCP-7150:
Ah, good, so you aren't going to kill me from thirst.
Dr. [REDACTED]:
No, we are not going to do that. Second, you will be tested on occasionally is the 05 council approves of it.
SCP-7150:
What kind of tests?
Dr. [REDACTED]:
I can't say. And finally You will be rewarded with a reasonable reward after proceeding with each test.
SCP-7150:
Oh good, I like a good treat.
Dr. [REDACTED]:
Well then, that's all I have to say apart from: I hope you have a nice stay here.
SCP-7150:
Thankyou Doctor, you have made me feel very welcome.
After that SCP-7150 never agreed to another interview with any Foundation personal.
Incident SCP-7150-1
Dr. [REDACTED] was testing SCP-7150 with SCP-7150-1 when the soundproof control was taken over by SCP-079. SCP-7150 was then able to breach containment (whilst in the possession of SCP-7150-1) and went on a rampage, mind controlling everyone he saw. MTF were called into the facility with special soundproof headphones. SCP-7150 was re-contained and SCP-7150-1 was confiscated and then re-contained. Everyone who was under control by SCP-7150 were locked in the breach shelter until the symptoms passed. After this incident the soundproofing was connected to its own generator and further precautions were put in place for SCP-079.
