The Hidden Bond
(Book 1 of the Unity Saga)
Prologue –Worlds Entwined
I’m so excited to finally write this prologue and present the completed version of my story. With this installment, the journey comes full circle. The story is eleven chapters long, framed by both a prologue and an epilogue, and it’s been one of the most rewarding writing projects I’ve ever taken on.
A brief history of how this project came to be: I initiated this project in February. It started with a plot thesis, and from there I worked closely with a partner to flesh out the story. I want to extend a special thank you to RoczaDeb. She was instrumental in helping me refine what I call my “foundational documents.” Her feedback challenged me to rethink confident choices, and those changes ultimately made the story stronger and more cohesive. She has an incredible library of her own stories, and I highly encourage you to check them out.
You’ll notice I use the term foundational documents. In total, I created about fourteen separate documents while developing this story. These included a plot thesis, crisis points, crisis scene breakdowns, character analyses, subplots, story outline notes, guides, and detailed chapter-by-chapter outlines.
The most important of these was what I call my world-building document. This story drops you—the reader—right into the fifth season of Arrow, at the midpoint of the season, with all the Arrow and Supergirl midpoints finally completed. That choice meant a lot of history had already unfolded in the background. I mapped out all of that unseen history so I could weave it into the narrative. Throughout the chapters, you’ll see elements of this world-building appear naturally, whether in flashbacks, dialogue, or subtle narrative cues.
I won’t share the world-building document itself—it contains too many spoilers—but I do want to highlight a key point to help you understand the story's setting.
This tale takes place on a consolidated Earth that merges the heroes of the Arrowverse. It is not Earth-Prime, as seen after the Crisis on Infinite Earths, nor is it Earth-1 or Earth-38. It is its own Earth, with its own history and unique continuity.
For this story, Arrow will serve as the anchor of the universe. That means the events here take place during Season 5 of Arrow. While this doesn’t directly change the timelines of The Flash or Legends of Tomorrow, it does shift Supergirl’s timeline significantly.
Here’s how it works: there is no Batgirl or Batwoman in this continuity. The Flash Season 1 still takes place within the same time frame as the show, which means Barry emerges as the Flash during Arrow Season 3. However, Supergirl’s timeline is advanced. Her Season 1—her emergence as Supergirl—occurs at the same time as Barry’s. By the time we reach Arrow Season 5, The Flash and Supergirl are both in their respective Season 3 arcs. Please keep that distinction in mind.
Although this story is set during the midseasons of these shows, the narrative itself is entirely original. I will draw from specific events and characters from canon, but only as background touchstones. The primary focus here is new content, new conflicts, and new dynamics.
Now, you may be wondering about canon. For the most part, canon outcomes remain the same, but the paths to those outcomes are altered. The introduction of Kara into Arrow’s world as early as Season 1 has ripple effects on both her character and Oliver’s, as well as the choices made around them. That’s why I created a detailed world-building document to track continuity and ensure characters develop in a way that makes sense. You’ll see, for example, that while Kara didn’t publicly emerge as Supergirl until Arrow Season 3, she wasn’t idle before that. The groundwork she laid during Arrow Seasons 1–3 will surface in this story.
Looking ahead, this is the first of three stories that form a trilogy. These stories take place back-to-back before the characters return to their own seasonal arcs. I don’t plan to write direct episode retellings; instead, these first three stories will stand as their own saga. Afterward, I plan to revisit and write prequels covering Arrow Seasons 1–5 and Supergirl Seasons 1–2, exploring how their worlds intertwine and affect each other. In total, this could result in six stories. Beyond that—I’m not sure where it will lead, but I’ll let the characters and world guide me.
This story took me months to complete. I began principal writing in late April 2025 and finished in mid-September 2025. It will take time to write the next installment, but I promise you this: I will never publish a story until it is fully complete.
I want to invite you now to step into this universe with me — to take a moment away from reality and enjoy the story. My motivation for writing this came from the incredible work other writers have done exploring the pairing of Oliver and Kara. Their stories inspired me; I only wanted to add my own voice to this unique pairing and see where these characters would take me.
A few quick notes for the comment section: constructive feedback and spirited disagreements are welcome — they help a story grow. Flaming, harassment, or mean-spirited attacks are not. If you’d prefer to send private thoughts, I can share my Discord handle later for direct messages.
Thank you for reading, for caring about these characters, and for joining me on this ride. Now—let’s begin.
