Legolas By Laura/WMG

Laura is the hippie elf chick from The One Ring To Rule Them All 3
The Elf Chick had said to have broken up with Legolas, which fits to what happened in the end when Legolas started to be Laura's boyfriend, she is shorter than him, we are not told her age in the flash movie and we are not told her race in the fanfiction.

Laura was murdered by Tara Gilesbie.
As Laura was typing it, Tara appeared behind her, wielding a "goffik blak" claymore with red lace. She shouts THERE CAN ONLY BE ONE BAD FANNFIC WRITER! "TEHRE CAN ONLY BE OEN BAD FANFCI WRITER!!1!1!" and then decapitates her, which is why it ends in mid-sentence.
 * Then who uploaded the fanfic?
 * Duh. Isn't it obvious? When Tara decapitated Laura, Laura's head fell on to the mouse or keyboard and caused the fanfic to be submitted.
 * Alternatively it's the same person who presses submit after somebody says Candle Jack and is taken a-
 * I support this theory.

Laura wrote this during a Heart Attack.
Laura realized she would be dead in a few minutes and she wanted to write a LotR fanfic before she died, so she wrote what she could. The end result was a severely condensed version of the story she would have written if she had more time. Apparently her last act was pressing the upload button. This author-sponsored mindrape has no other justification. Ow my head.
 * That is a very depressing thought. I think I prefer "she was really stupid".
 * And imagine her spirit watching, very sad, but happy. "At least I brought people laughter with my fanfic...and at least, I was remembered."

The fic is Based on a Dream.
Much like My Inner Life, the fic chronicles the author's adventures in fangirl wish fulfillment land. The ending was so abrupt because that's where she woke up and she couldn't come up with an ending of her own.

Laura was kidnapped by Slender Man at the end.
This would go with the theory that Slender Man goes after Mary-Sue authors, and explain why it ends mid-sentence. Maybe she was being stalked by Slender Man and was too nervous to fix all the spelling and grammar errors.
