Uhm...if you wrote it, why would it be Lord of the Rings? You planning on plagiarizing it or something? I find your question somewhat confusing and baffling.
Are you afraid that you'll be temted to write the same story, because you read Lord of the Rings and it is your favorite book?
You are not cklear with your details. In fact, you've given no details at all, so I've really nothing to go on.
Why can't you just think of a story and write it? Why does it have to be anything other then your own creation?
You know, it's very much annoying me that you don't know to capitalize races. The words Elf, Elfs, Elves, Elflings, and Elvish should always be capitalized. You also did not capitalize your genre, and you used abbreviations and you used a contraction. Quite a few errors for just one sentence.
We as writers make mistakes, sure, but we should at least have a basic graspe on Grammar rules, enough to write a single sentance.
You are worrying about writing a novel that'll get mistaken for someone else's novel, but you don't even have a basic grasp on Grammar rules. There are four grammar rules you've ignored in your question, and that's just one sentance. If you have this much trouble with one sentance, how will you write a novel to begin with.
Harsh, yes, but, it shows that you've yet to sit down and wite ANYTHING. You have no practice in the art of writing, you have no knowledge of how to write, and you are already jumping ahead and worrying about writing a story similar to someone else's.
You have plenty of years to worry about that. Get some writing practice in first. Learn Grammar. Figure out the basics of storytelling. Then you can focus on writing your tory, and then in 3 or 4 years, AFTER you've learned grammar, written a book, and edited and revised it a few times, THEN you can start worrying about your novel vs someone else's novel.
Horse before the cart and all that, you know?
But let's answer your question directly.
Uhm... you want to write a Fantasy novel.
You want to include Elves.
And you want to include Wizards.
You are afraid it'll be too much like Lord of the Rinds.
Though I'm not sure why.
And you asked me.
Is it because I write Fantasy? About Elves? And Wizards? But it's not like Lord of the Rings?
I write Fantasy.
I write Elves.
I write Wizards.
But I suppose the real question here is, is what I write like Lord of the Rings?
I don't know, let's find out...
It's about a transvestite wizard Elf who dresses like a female Liberace and whose primary lover is a purple Unicorn and secondary lover is a half-Elf/half-Demon who from the waist up looks like an Elf, but he keeps his legs and feet hidden because he has the legs and hooves of a Cotswald sheep, with long silkie white whool. They live in a Steampunk style universe set mostly in the 900s and 1400s and 1970s, in Maine & Quebec, where there exists portals to castles in Scotland, portals to the past (such as Ancient Egypt and Persia) portals to the future (such as the time they went head to head against 1920s rum running gangsters) and some portals zip them across the galaxy where they meet Lovecraft inspired squid headed aliens.
They frequently find themselves in a White Rock's insane asylum in the year 2525, when the world is on the brink of self destruction as the moon come hurtling towards the Earth.
They sometimes travel with a half-Dwarf/half-Troll and sometimes with a Vampire Leprechaun, and sometimes with green skinned, pink haired Flower Gnomes.
Several times they visit the North Pole to make attempts at rescuing the enslaved Cookie Elves from the sweat shop slave factories of the evil red robed Leprechaun Santa Claus who obsessively gives shoes to children and his blood thirsty Phookan partner Krumpas who obsessively eats children.
The creature races include Phookas, FarDarrings, EachUsty, Ghuillie Dhu, Tweegs, and other creatures from Scottish mythology. They fly around the world on a purple pirate ship named The-Rent-A-Prize, Captained by a Gnome named Quirk with his first officer Schlock, and a parrot named Dr Macaw. Some of the villains fly around in Zeppelins. Other villains ride in on ice powered stealth ships and shot 1960s style ray guns.
Humans are always evil, and in spite of it being the 1400s are armed with 20th century guns. In this version of Maine & Quebec, taverns and wild west saloons can be found in every city, yes, Maine & Quebec are teaming with cities in this alternate version of the 1400s Earth.
And the most feared Necromancer on the planet is scared of dead things and faints at the sight of blood and has a fetish for being tied to trees and BDSM tortured by Unicorns.
The Universe is ruled by talking cats, who are trying to find The Grand High Emperor of the Triple Planets, who is a Pink Necromancer who long ago was murdered by a tiny pink jelly fish from outer space that ate his brain and now lives in his head and controls his body.
The cats are being hunted by 8 foot tall bird men from Planet Ptarmagin, who live in gold plated places ontop of floating islands, and toss their victims to the surface below, into the mushroom forest when murshrooms grow 100 feet tall and the deadliest thing you'll meet are man eating fuzzy catipliers 30 feet long and cute fluffy, fuzzy wuzzy, blood sucking bunny rabbits.
Does that sound like Lord of the Rings to you?
I don't know.
Do you want to know why I don't know?
I have never read Lord of the Rings. Shocking. Yes. I know.
So, I have no idea if the Fantasy I write is anything like Lord of the Rings or not, seeing how I don't know what Lord of the Rings is.
I am however a Dungeons and Dragons Dungeon Master who ran a SpellJammer session for well over a decade and kept detailed game session notes of every game and later used those notes to create the novels of the series mentioned above.
And there you have it: how I wrote an entire series of Fantasy novels that is NOT Lord of the Rings and yet, still has Elves and wizards in it.
What do you want to become?
What did you do today to step closer to that goal?
Whatever you do, be your best at it!
And remember to have yourself a great and wonderfully glorious day!
