You were on vacation in the Dakota's, on an expedition in the rural countryside, rowing down a large canyon in a dinky little raft. The canyon's walls reach higher than you can see, but you know that it goes back upwards. You're not worried... until the waters get rough. The river begins to run faster, the canyon walls shaking violently, rocks plummeting down towards you, barely missing contact with you as you tumble down the raging river. You're driven into a cavern and sealed inside by the fall of a massive stone...

Things have gone from bad to worse. The walls tremble around you, the cavern getting smaller and smaller as you fly down the rapids on your tiny raft. Then you see it... a waterfall. You try desperately to escape, rowing as hard as you can, but to no avail... You fall over the edge, plunging thousands of feet below...

... After a while, you slowly open your eyes to find the clear blue sky above you, with strange conifer trees everywhere. You hear strange unfamiliar animal sounds, and everything feels off...

Welcome to the Land of the Lost.
