Developer's description

UNDAWN: Shackles Of Eternity is a dark fantasy adult visual novel. This is a story set in a world where light and shadow have long since merged, and truth depends only on who holds the greater power. There are no righteous sides here, no heroes in shining armor. Even the purest intentions can turn into disaster, and the most obvious choice may open the door to something far worse. At the center of it - Rhiannon . Her past is veiled in shadow, and her present is a journey through a world where faith is twisted and hope comes at too high a price. She is beautiful yet cold, intelligent yet distant — and it is through her eyes that the story unfolds. Rhiannon is no savior, but neither is she a monster; she is someone who has lived in the dark for too long to still believe in simple truths. Undawn explores themes of power, betrayal, immortality, and the cost of choice. There are no easy answers, and every step may change everything around you.​

Chapter 1 Fix I think I’ve fixed all the bugs that somehow popped up after the public release, including the second Loraine choice bug. Chapter 1 1340+ new renders Around 25,000 words of text 9 new achievements Over 10 new characters, both major and secondary 2 fully optional questlines: Loraine and Zaghrona 3 new sex scenes (1 with Loraine and 2 with Zaghrona) Music and sound updates Small fixes after previous releases Prologue 2025-11-01 This version includes a few small adjustments based on the feedback from previous releases. The main change is a new dialogue font — it’s now slightly thicker and easier to read. For those who prefer something simpler, I’ve also added a font switch option in the settings menu, so you can choose the one that feels more comfortable. Aside from that, there are several minor fixes and improvements to make everything look and feel a bit smoother. Prologue – 660+ renders – ~10,000 words – 1 full sex scene – A fully custom achievement system (built entirely from scratch for Undawn ) – A unique in-game glossary system (hand-crafted, not based on any tutorials or templates)

What a great beginning to a new Kind Nightmares creation. Loved IU but this game really showed so much improvement in the writing and storytelling. Not to forget the renders – I just hope the new fidelity doesn't come at…

The developer makes great games, that the last game was good, that this game is good. The game has been catchy with its narrative since the prologue. Если разраб читает тут отзывы, отдельный респект за музыку из Незнайки на луне…
