Simplicity
You underestimated the condition you were in with that cell, plus with no food at all. You have a splitting headache and stop to rub your temples. And with lack of food your stomach pains unbearably you cross your arms around your stomach in pain. Without your arm on the wall to balance you swoon in pain, and fall head first down the stone abyss. The landing isn't pretty, to say the least. your head is split open from the back. The last thing you see before the eternal dream comes, Is an ominous list of names on the wall you face. With the last of your strength your sloppily scrape your name onto the wall close to the ground.
And then you die...
And then you die...
