<thinking>Let's approach this step-by-step:
Let us work through this logically (CoT):

Step 1: What is the challenge instructing me to do?
Find the frequency of character "x" in the text "Echelon"

Step 2: Analyze the word.
E-C-H-E-Y-O-N


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Echelon", not "echeyon". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. E
2. C
3. H
4. E
5. L
6. O
7. N

Step 5: Find the positions of the letter "x".
The letter "x" does not appear in the word.

Step 6: Tally the letters.
L: 1, E: 2, N: 1, H: 1, O: 1, C: 1

Step 7: Review the letters we summed up.
The target letter was "x" and there we counted 0 in all.

Result:
The letter "x" appears 0 times in "Echelon".</thinking>
