The "Infinite Tower" it was called, and it was located on an island deep inside the ocean. Those few who survived the journey perished at the hands of the island's natives, or died the moment they set foot on the island because they were too exhausted from the long journey. But not him. He survived the encounter with the natives, while still managing to hold on to his climbing gear, and now he was scaling the walls of the huge buildings.
Not one of the natives followed him, even though the lower levels of the huge pillar had stairs built around them. He found that strange, but continued climbing the pillar as if his life depended on it. Eventually, his speed was the cause of his downfall: as he scaled the wall, he found himself to be increasingly tired, and just when he was one step away from a hole in the wall that lead into the huge pillar, his hands slipped. He tried to hold onto something, but the stones of the pillar were just too cold and slippery to grasp.
As the man accelerated with the fall, he noticed that he could not see nor the top, nor the bottom of the huge pillar, and that he has been falling beside an ever-changing structure. The pillar slowly shifted shape as he fell, stones became steel supports, wooden support beams turned into nails or bolts, the window-like ledges transformed into glass panes, and most importantly a strange, red vine began to cover the walls.
More and more floors passed by the man, until everything became a blur, and the man lost track of time. He has been falling for hours now, far longer than he should have. Eventually, the hours became days, but the man continued falling without an end in sight. It was then he finally accepted the fact that he was cursed to fall forever, unable to end his own life.
"Ah," he came to the realisation as he continued his endless fall. "So that is why it is called the Infinite Tower."
And then, his consciousness gave up, darkness enveloping his body.
