I think this is a good place if you have any questions about the stuff I wrote.
The first two I basically wrote spontaneously. You could say they wrote themselves. I just wrote as it came to my mind and things just unfolded from there. Both written for /r/writingprompts.
The last one took a bit of planning. I had already planned on adding some violent ends. I was also planning on adding more fantastical and cosmic horror elements by having the character enter the realm of the god Tlaxaklotl (a name derived from meso-american stylization, specifically similar to Quetzalcoatl) which would be a nightmarish landscape with the god itself being an amorphous, tentacled black blob covering most of the sky, reminiscent of some Lovecraftian deity. But putting down all of that to words was becoming tedious so I cut it short and kept it simple. Another motivation for simplifying the story was that, as a powerful god, Tlaxaklotl doesn't really care much about mortal beings and prefers that have all of his business carried out by his priests who act as his agent.
I created a fully fantastical setting because writing something based in reality would require me to adhere to existing tropes that I did not feel confident tackling. Thus, almost all names are fictional names I thought up.
