It all started with a fish. It was an ordinary fish, swimming peacefully in an ordinary lake. Or was it? Something peculiar happened on that day, something, supernatural. In the lake there is an underwater arc, nothing famous, nothing special, just an arc made of rock, coral, and the usual stuff. Yet, on that day, it was extraordinary. Normally, the water would flow coherently under the arc, following the water patterns and such; yet on that day, the water underneath the arc flowed in the opposite direction, perpendicular to the surrounding water. And when the fish swam through, well, to it nothing changed, it just went from water to water. But it was different water. A different land. For in that moment, against all laws of nature, that arc had become a portal. It was a minor portal, but it was a harbinger of something greater, something universal. Something, dark.
