Game Overview
Celestia: Chain of Fate is a romance-fantasy visual novel that delivers a captivating player driven narrative.
The perfect life you’ve known as a daughter of a Duke is about to change forever. With the revelation of your new hybrid identity, as a descendant of Angelus and Daemon, you must learn to live in a new world.
Compelled to accept an invitation to the Academy of Celestia to explore the world of magic, you must set out on a fresh journey in a world filled with demons and angels.
Uncover the secrets of your family history and learn to control the magical abilities you hold. Along the way, you’ll have the chance to develop relationships with one of three romanceable characters, each with their own unique traits and personalities.
It’s down to you to hold your friendships and advance your love interests while also prioritising your education. Remember not to neglect your studies as you’ll need to overcome a series of challenges to graduate!
The premise makes the game sound like something I’d enjoy. However, at least as of now, the official site says the release date is “Coming Soon”, while the link to a video titled Celestia: Chain of Fate | Release Date Announcement Trailer is right under that “Coming Soon”. The shorter blurb for the game on the site also says (emphasis mine):
A romance-fantasy visual novel that delivers a captivating player driven narrative. Enrol at Celestia Academy and uncover your heritage and identity as the descendant of Angelus and Daemon. Delve into a fantastical realm and unearth your magical potential as a hybrid. Forge new friendships and build affections based on your love interests.
I hope the actual game pays more attention to detail than this :(
Also fun note: description makes me think that pseudo-medieval generic fantasy setting, skimming the trailer shows me the world has mobile phones and texting.
