Day 1,577

From the outside it looked like another disused warehouse, crumbling around the edges and ivy slowly consuming it from one end. It wasn't always like this - it was once the lower city's only museum focusing solely on the harbour's legends and history.

One entire wall was a dedicated timeline from the earliest recorded settlements to the latest newspaper headline dating some two years ago when it was shut down. There were too many cases of missing children in the area for anybody to want to visit and they couldn't afford to stay open.

Coincidentally a few months later the number of children going missing dropped to nothing. The staff were interrogated by the local community and confessed to knowing next to nothing. A few rumours came and went regarding certain people who frequented there and in the end it was all dropped and forgotten.

Then one day - almost exactly a year after it shut down - a couple of bored teens broke in and were never seen again. More and more people went missing each week until the numbers were as high as they'd been when the museum was in full swing.

People still suspected the staff but not one of them looked deeper into the taxidermied creatures that were left to rot and saw that some of the wet specimens weren't quite as lifeless as others. The giant pacific octopus had always twitched about in its tank, too eager for more curious people to come wandering in and eventually growing impatient enough to leave the tank completely.

It wasn't alone either - but it was the only one that could leave. Occasionally it would dump whatever it didn't feel like eating into the tanks of other creatures, most notably the great white shark that would otherwise thump about in the tank and draw unnecessary attention to them all.
