situated at least 1 kilometer from any other dark area.
I don't think the foundation could manage that while the thing is on Earth, unless you change it "enclosed dark area". Even then, how could they make sure there weren't any 23m caves 1 km underground? Changing it to "enclosed artificial dark area" would make it managable, but that would still require its own dedicated site.
However, the song will cease within 10-20 seconds if a witness or witnesses attempt to whistle, hum, sing, or otherwise engage with SCP-1219's tune, and the witness(es) will be dismembered (stripped primarily of organs related to vocalization)
- What if they just talk over the whistle, totally unrealted to the tune? Or say something like "Who's there?"
- What if they sing a different song?
- What if they turn on a recording of the same song?
SCP-1219 has been found capable of instantaneous transfer within an area of approximately 12km.
That should be "within a distance of approximately 1km."
