Don't Look For Us, by Dimitri of the Silver Blade.
If anyone find this, stop reading now and RUN. Read the rest later on very, very dry land. Just GO! I can't believe we thought they were merfolk... They surrounded the ship, scratching and clawing. Started to sing, just like the chest. A deadly harmony... They're dragging us down. I'm locked in my cabin but those weapon... things... will break through soon. They have the Silver Blade now. They have us. I hope you never find the Silver Blade. If you do, it means it's already too late. A dark legend has found you. You belong to the Sirens.
