Hey bro, thank you so much for the feedback! I definitely wanted to include some elements that would allow another author to roll with it. I've still got some learning to do on Psyber X lore but this was a really fun way to start that journey. Looking forward to writing more!
I'll DM you regarding the sigils thing, I wanted to make some sort of reference to Myria and blend the walls between those two walls, just some random headcannon I threw in, we can discuss context :)
Thanks again!
