Hello Academians!
It’s me, Roman Hearthstone, and this time, I’m bringing to you The Puzzled Dragon, in which I will give you a puzzle to solve, which can be both fun, and a great way to boost your brain as well. Let’s get started!

First of all, I'd like to say congratulations to Luna Circle for sending me the answer to the last puzzle the quickest! Great job, Luna!

My cipher last week proved to be very popular, therefore, I am bringing to you another one: a keyword cipher. This time, I won't be giving you the key, just the keyword. You can make your own key by writing out the keyword, removing any repeated letters, and then writing the unused letters of the alphabet behind it. Match all of these with the letters of the alphabet in the correct order and tadamm you have yourself a nice little key. If my explanation confuses you, I found this site to be very helpful in understanding the cipher.

Keyword: Preceptor

Now, your job is to decode the following list of names, and tell me which one isn't the dragon name of one of our lovely preceptors.

1. SBTSDQ
2. BDCCTJ
3. UNEBDJ
4. PEEPHKJ
5. QKHPQSP

If you think you have the correct answer, including the list of decoded names and the one not belonging to a precetor, make sure to send it to me in a letter called Puzzles! The quickest dragonet, whoever gets their solution in the fastest will get a special little prize too. Have fun!
