7th century: "I, master of the runes(?) conceal here runes of power. Incessantly (plagued by) maleficence,(doomed to) insidious death (is) he who breaks this (monument)."

This place is not a place of honor. No highly esteemed deed is commemorated here. What is here was dangerous and repulsive to us. The danger is still present, in your time, as it was in ours. The danger is unleashed only if you substantially disturb this place physically.

God, I love Sandia National Labs for coming up with such great creepypasta: https://en.wikipedia.org/wiki/Long-term_nuclear_waste_warning_messages

What if climate change was caused mostly by this guy cursing the wind...

where is this? doesn't look like any runestone i've ever seen. there should be remnants of a border visible at the bottom.

The Björketorp Runestone in Blekinge, Sweden.
- oh its hella old, that's why.
  also, the interpretation of the ur-nordic listed on the swedish wiki is basically "if you ruin my rock you are a beta male":
  Ärofulla runors rad dolde jag här, mäktiga runor. Rastlös av arghet [d.v.s. perversitet], död genom list skall den bli som bryter detta. Jag spår fördärv.
  Ristaren förutspår att minnesmärkets eventuella förstörare ska drabbas av förbannelsen. "Arghet", fornnordiska ergi, betyder 'omanlighet, feghet''.
  translated:
  "the carver predicts that the one who destroys the stone will be struck the curse of ergi, 'unmanliness', 'cowardice'."

Reminds me of Valheim.

The translation is not very accurate. It should be read something like this:
be me rune master
concealing runes of power
Chad comes and breaks the monument
plagueOfMaleficence.jpg
insidiousDeath.exe
lmao why are Chads like this?
[Insert pepe]
- When you try to lie to IT support.
  “Are you sure you didn’t download and run InsidiousDeath.exe?”
They weren't stupid they just didn't know any better. There's a difference, and it's an important one in these troubled times.
So many ancient writings are shitposts though. This could very well just be OOP trolling the kind of people who would be scared of such a message, or even making a joke we no longer have the references for.
- Some Roman general “Look, there’s no such GODDAMN THING AS RUNE STONES. Now go take that fucking Druid village or I will give you something to be scared about.”
how is that different than today? hint: it’s not.
