Summary

2016. Inre Island. A seemingly idyllic, modern island in the middle of the Atlantic Ocean. A constant tranquil breeze along a mild climate, and a well-off society embracing a harmonious way of life. Its citizens often refer to the island as their very own miracle, counting themselves lucky to have been born on it. Tourism is low despite Inre being a highly desired travel destination, and for good reason. Not only is it a trip only the rich can afford, a rigorous regime means a special visa is required for entry. 2018. Over a course of six months, a lethal biological attack claims a significant amount of lives. While tragedy occupies people's minds to the brim, a controlling governmental plan is constructed and put into motion. All to prevent such attacks from ever occurring again. The following years, Inre Island's citizens face unexpected change from their usual ways. On a sombre day – damp, dark, and horrifying – the internet is shut down, leaving the island disconnected from the world around it. 2020 - present. After a long internet-less spring tinged with uncertainty, a new system to replace it with is introduced. A new "internet" along digital setbacks result in major changes to everyday life. Unable to adapt, many find themselves spiritually stuck in a world that no longer exists. Suddenly, the island appears shrouded in mysteries. The closed hearts are many. A select few want a way out. But most want to reset and forget. People who never would've met, meet. People who never would've loved, love. An island that had never known sadness, knows it now. Cerulean Days is set in 2020, and follows two outliers of society – mellow Michael and competent Séverine – as they discover the true effects of 2018. Amidst tragedy of lost friends and family bonds are grown, solace is found, feelings blossom, truth is discovered, and conspiracies are seemingly unraveled. Hearts in need of mending await you. Welcome to Inre Island. [From Kickstarter]
