On Tapas I suggest RachelDeNucci's The Black Robin
I was one of the beta readers for it and it has some really cool and well written lore in it. She has been working on it for a long time now and finally started releasing it to the world. I don't want to say much so I don't reveal any spoilers, but I highly suggest this.
Another story she is writing is technically a sequel that comes MANY generations after The Black Robin, so I also link it here as well.
