Ok, if it's your first time, then it's fine. I have a thread open for new writers who joined tapas that's less restraining. Here, I give you a prompt, but there, you can write whatever you want, as long as it meets the criteria of being focused on a power and about 150-350 words in length.
However if you would like to continue with a prompt, just let me know and I'll DM you the details.
