Pillar 7 is the shortest pillar. It also explains the method it uses to encrypt the alphabetic text. It is presumably a pillar to introduce participants to the concepts of encryption.
It contains an unexplained numerical grid near the top of the pillar.
Numerical Grid
At the top of the pillar is a grid of numbers of 5 rows and 26 columns. A triangular glyph surrounds a number (rather than pointing as in other pillars).

Transposition (Caesar) cipher
The remainder of the pillar is filled with a simple cipher - the Caesar cipher.
At the top is a plaintext which makes an obvious reference to Caesar:
| A LETTER SHIFT A CIPHER MAKES
A FAMOUS ROMANS NAME IT TAKES |
Then below that, it pictorially depicts a letter shift. In this example, A>B, B>C, C>D and so on, with Z>A.
Below this is a cipher text:

Using a simple online Caeser cipher calculator, this decrypts using various shifts to read
|
(With a shift of 1) A LETTER SHIFT A CIPHER MAKES A FAMOUS ROMANS NAME IT TAKES
A SHIFT OF TWO YOU NOW CAN BREAK BUT OTHER MOVES A CODE CAN MAKE
HOWEVER THEY BE SWAPPED ABOUT A KUFA MAN COULD FIND THEM OUT |
Base
A string of numbers runs around the base.
