<thinking>Let's approach this step-by-step:
We should go through this systematically (CoT):

Step 1: What does the inquiry demanding me to do?
Determine the occurrence of character "z" in the string "Ephemeral"

Step 2: Break down the word.
E-K-H-E-M-E-R-A-L


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

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

1. E
2. P
3. H
4. E
5. M
6. E
7. R
8. A
9. L

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

Step 6: Enumerate the letters.
L: 1, P: 1, A: 1, E: 3, R: 1, M: 1, H: 1

Step 7: Examine the letters we quantified.
The selected letter was "z" and there we identified 0 in total.
