This puzzle requires the “Direct Access Terminal” page, the Abronath disc and the red Y.A.R.N.
The list of numbers can give six different methods for wrapping the Y.A.R.N. around the Abronath. Be alert\! The arrangement of numbers on the Abronath are mirrored between the front and back sides. And when looking at numbers written upside down it’s easy to mix up 6’s and 9’s.
Use each line of numbers as a guide for wrapping the Y.A.R.N. around the Abronath. This will result in the Y.A.R.N. creating familiar shapes.
Each correct wrapping of the Abronath will create familiar shapes on the front and back sides of it.
The correct wrappings of the Abronath can help you determine a letter that corresponds to each shape shown on the locked direct access panel.
When the Y.A.R.N. is wrapped around the Abronath in the order given by the first listed numbers, 6315038, one side of the disc will form the third shape shown on the locked access panel, and the other side of the disc will form a letter A.
ANSWER REVEAL: The specific method for wrapping the Y.A.R.N around the Abronath is to have the front side of the disc facing you, then place the Y.A.R.N. in the starting numbered notch so that the end of the string is on the front side. This makes it so the length of string connecting the first and second notches travels along the back side of the disc, then the length of string connecting the second and third notches travels on the front of the disc, and so on until the string travels to all the listed numbers, in the order listed. The first line of numbers, 6315038, forms a shape on the front side of the disc that matches the third shape shown on the locked direct access panel. The shape formed on the back of the disc is a letter A. So the third letter of the answer is A. Repeating this method for each line of numbers gives six different letters and puts them in order to spell the answer WEAPON. Looking at the “spiral galaxy” envelope, weapon is synonymous with MUNITION. So MUNITION is one of the three keywords needed to access the envelope.
