I'd nearly given up on this story, but coming across some painful Mary Sue stories has prompted me to continue with this.
Disclaimer – I don't own Lord of the Rings. If you still want to Sue me, please email me first so I may leave the country.
Vethedwath squinted through the snow. Yes, there was definitely a hobbit-sized lump attatched to Boromir's back that wasn't there a moment ago.
Rolling her eyes, she took out a throwing knife and easily destroyed the Sue.
A deep chanting voice caught her attention, and she ran to the front in case it was a rare Gary Stu, absently stabbing the elf woman that popped up, saying "There is-eek!"
"There is a fell voice on the air." Legolas said, straining to hear more.
"It's Saruman!" Gandalf yelled, before an avalanche of rocks came down, narrowly missing them.
"He's trying to bring down the mountain; Gandalf, we must turn back!"
"No." Gandalf climbed up on top of the snow bank, and began chanting. A feminine voice joined him.
Vethedwath sidled up and bumped her off the edge. Gandalf continued chanting alone. It wasn't enough, though, and some lightning hit the mountain, causing an avalanche of rocks and snow to cover them.
All the fellowship, plus Vethedwath dug themselves out easily, but Aragorn suddenly became frantic and began digging.
"Aragorn, what are you doing?" the Sue Slayer asked resignedly.
"It is Andodulin, my love, my life. She is trapped within the snow!"
"Leave her Aragorn." Vethedwath said sharply, "she is evil."
"But – " Aragorn got no further, before Vethedwath smacked him round the head, and he shook it to clear it. "Thank you, Vethedwath. I do not know what came over me."
"We must get off the mountain!" Boromir shouted. "Make for the gap of Rohan, and take the West road to our city – my city!" he amended, as the woman next to him fell to the ground with a sword in her throat.
"The Gap of Rohan takes us too close to Isenguard!" Aragorn argued.
"Yes, my father aieeeeeeee!" her shriek was lost at the bottom of the mountain.
"If we cannot pass over the mountain, let us go under it! Let us go through the mines of Moria!" Gimli said.
"Let the Ringbearer decide." Gandalf said eventually, and all eyes turned to the small hobbit lass being held by Aragorn, before switching to Frodo hastily as she was slain.
"We will go through the mines."
