Well the writing at the top is easy enough to reckon because the phrase itself is well-known. It comes from a stone in Björketorp Sweden and dates from the 6th or 7th century. Of course the original was written in the Elder Futhark. That this scroll should display it so plainly in Latin characters (albeit with a strange hand) is clearly intended to provide some sort of clue or key. The phrase "Haidz runo runu, falh'k hedra ginnarunaz" translates literally from the Norse as "I, master of the runes conceal here runes of power."
Now in Norse the word "rune" is a bit tricky because it has multiple meanings depending upon the context. It can mean a secret, to hide something, or to write a message. "Runes of power" sounds a bit dramatic. Then again you did just talk to an ivory-skinned girl in a shadowy cape who disappeared into the mist. So all bets are off at this point.
But you say there's a machine, behind the door. So let's have a look at the door.
It looks at first as if we will fare no better, but then I see a pattern emerging. [Thank goodness for Ni] At the top of the door is a phrase in Latin.
Queste parole di colore oscuro
vid’ ïo scritte al sommo d’una porta
per ch’io: "Maestro, il senso lor m’è duro".
This translates as:
These words in sombre color I beheld
Written upon the summit of a gate;
When I: "Their sense is, Master, hard to me!"
And so I think we've duly noted that the words written below on the door are in sombre color, and well, erm "hard to me!"
This is what they look like:
So what could it mean?
I will have to ponder on it some. For now I think it's best we take a look at that machine. Hopefully the controls are more plainly marked than this door.
(OK Vizier, just to let you know - putting funny letters on the door in the very first lines of the story is like dangling red meat in front of me. So I'm afraid you're going to have to put up with some of this nonsense for now. Unfortunately I've got to go to bed, but this is going to be fun. Great idea.)
I decided to seek the help of an expert in strange inscriptions and languages. Thank goodness the INFJ cafe has such specialists. I walk up to Runescribe and explain the situation to him. Then I show him the parchment. I point out that we still don't know if the inhabitants of this strange place are friends or foes and that every minute wasted could place all the INFJs in jeopardy. We need to find out how to deal with the machine and see if we can get out of here....but who can do it?
