Cypher Scrolls – these were the common means of communication used by the Dark Elves. They often appeared in the game in Link's previous life, but these were just worthless gray items because the messages on the scrolls were undecipherable, rendering them useless.
Link inspected the Cypher Scroll in detail. What he could deduce from it was the fact that it contained about a thousand words written in Dark Elven letters, although their meaning remained impenetrable to him.
With the help of the gaming system, Link could understand the meaning of each individual word, but a string of words was still incomprehensible. For example, there was a sentence that went the banana peel is bigger than the banana fruit. Link was at a loss as to what these words could actually mean.
This looks like a command letter, Link thought, too bad I don't have the key to unlock this code!
