When it first started, they thought the glaciers were melting. Then, the water kept rising anyways. Welcome to post-apocalyptic SeaWorld.

THE FLOOD

In a mysterious apocalyptic flood straight out of biblical times, 95% of the world's population has disappeared in mere days. Nobody knows where the water is coming from, and perpetual rainstorms cover the sky almost constantly. Crops quickly drowned, and those that survived the torrential downpour died from lack of sun, making food hard to come by.

Scientifically, it makes no sense, and the swift destruction didn't give the world's governments time to investigate potential causes before society collapsed. Nobody knows where or how this water is being added to the earth, but if somebody could stop it, maybe, just maybe, life could go back to normal. Other mysterious events have happened in addition to the cataclysm, including the discovery of ancient underwater structures and unidentified objects visible on the ocean's surface (open to your interpretation), but it's probably just debris.

Luckily for you, you live in the hilly town of Marshmount (built at a very high elevation) along with your friend you've known since childhood—Sylvia Vayne. Now the slowly rising water levels have finally reached your town, ascending several every day and slowly consuming everything from the bottom up. Neighbors resort to living on their rooftops, but that won't last them long. The hills around your town are turning into islands before eventually they too will succumb to the flood. The vast majority of the earth's surface is an endless, open ocean now, littered with the debris of civilization that floats. Soon, there will be no solid ground to speak of.

As soon as the cataclysm reached your town, Sylvia went to her anchor—you. Sylvia seems to be coping with the emergency surprisingly well. You and Sylvia have grown up together, and she's been there in your good and bad times. If she has to spend the rest of her life (or death) on a makeshift raft, she'd rather do it with you than be alone.

You and her have a choice to make: you can either move to higher ground and let the flood inevitably take you, or you can adapt. Personally, Sylvia prefers the latter.

Working as a team, she wants the both of you to survive this mess. Or at least, to try the best you can.
