A letter from the all seeing one

SCP XXXX

Object class:Keter

Special Containment Procedures: SCP XXXX should be kept in a filing cabinet at site 19 after the event of SCP XXXX /1 (see addendum SCP XXXX/1) SCP XXXX should be kept on a table inside an envelope in a regular human holding containment cell at site 19.
The cell needs to be monitored by video surveillance at all times, one level 3 security guard informed of SCP XXXXs properties should be stationed in front of the cell at all times.
every document, picture, video footage or audio footage of SCP XXXX and or SCP XXXX-1 (including this file) should be copied and the older version should be destroyed by incineration (It is highly suggested not to keep documentation about SCP XXXX and or XXXX-1 in digital form) if not the document in question will begin to manifest similar properties as SCP XXXX, if that happens the document should be destroyed as soon as possible, if destruction is not currently available the document should be named SCP XXXX Alpha and scheduled for destruction via incineration.

Description.
SCP XXXX is a sheet of paper of A4 format with the title of “My letter to you” and the content of which is written in scribbled unreadable lines.
Signed author of the text is “I, Nikola Tesla”

Anomalous properties of SCP XXXX are manifested in a way that the person viewing SCP XXXX starts to see the scribbled lines forming into normal text with an entity calling itself “the overseer” speaking to the person reading the text (see test log SCP XXXX/1)
SCP XXXX is indestructible by any means.

Another anomalous property of SCP XXXX is that it serves as a “beacon” to which the SCP XXXX-1 can travel (see SCP XXXX-1 interview log/1).
SCP XXXX is a humanoid shapeshifter possesses a great intellect far greater than the normal intellect of a human being, besides its intellect SCP XXXX-1 possesses great knowledge of basically everything that it has been asked.
Usually if in its humanoid form SCP XXXX-1 would wear the clothes corresponding to the dressing standard of the time it is appearing in.
Beside shape-shifting, SCP XXXX possesses abilities to materialize small objects in its hands (like apples and bottled water) (see interview log SCP XXXX-1)
After the materialization of the entity was finished and the SCP XXXX/1 event was concluded SCP XXXX-1 would sit on a chair present in the containment cell and wait for approximately 30 minutes until the “meeting” starts.
If the meeting doesn’t start in 5 minutes SCP XXXX-1 would look at the video monitoring camera and ask in a polite tone the person currently looking at the video feed (addressing it by its 1st name) to call the person with which the SCP XXXX-1 has arranged the meeting.
If the “meeting” doesn’t happen SCP XXXX-1 would slowly fade out.
If the person that SCP XXXX-1 has arranged the “meeting” has come SCP XXXX-1 would sit next to the person and require from the person to start asking questions
Until his death Dr. Joseph Brown was the “person” with which SCP XXXX-1 would arrange meetings, after his death, SCP XXXX-1 chose Dr. Alexandra Miller as the new “person” with which SCP XXXX would arrange meetings.

Until the time of 10. March 2019. there was only 1 meeting between SCP XXXX-1 and other “person” Dr. Alexander Jones conducted on the 10.July 1958. (see “meeting log /1”).
After March. 10. 2019. SCP XXXX-1 established a routine of breaks between “meetings” being around 5 years.
Up until now, there were only 2 containment breaches involving SCP XXXX the first one taking time during the 1st event of SCP XXXX/1 and the second one happening on ██. ████████ involving ████████.

Retrieval
SCP XXXX was retrieved on 7th January 1943 after the death of Nikola Tesla by MTF IOTA-10(damn feds) along SCP XXXX more anomalies were recovered such as ████████.
