Dragons have been done to death. But I do like the Unicorn Idea. I'm going to quote Foisair's idea first and then put how I would set it up below it in purple. My reasoning for my ideas will be under the purple text in black. Since it's both our ideas and my reasoning this post gets a bit long. ^_^;
The world started out as any typical medieval fantasy world with all its creatures and races. Every magical creature was hunted, from the great and powerful dragons to the most innocent of unicorns. Having the ability to fly, the dragons, gryphons and others fled the land until only Unicorns and Mortals remained. The unicorns, being prisoners of the earth, could only flee so far until their way was blocked by either shore or mountain. Once the horned horses were cornered, they fled no longer. Some say a wizard transformed them. Others say that a unicorn killed a man defending itself and that all its pure magic turned against the creature causing it to change. The reason why all Unicorns have become carnivorous monsters and are feared more than wolves or bears is simple. The Unicorns are Omnivores who are sick of dying and cannot graze without being slain.
Innocence is a luxuary the unicorns could no longer afford. Diplomacy is an action Mortals will not acknowledge because of years of hardship and social exile. Had Mortals and Mysticals lived side by side in harmony from the dawn of time, the present would be different. Now, Unicorns are no longer vegetarians and Mortals are no longer simple farmers, fishers, or shepards. Now, There are too many lives lost on both sides to avoid war.
What madness! When has the simple act of living become a crime in the eyes of the lesser races? If we live in a place they like, we fall by their swords even if we were there for generations. If we dare to eat, we are slain because they want to feed their pets in that area. They don't seem to care in the slightest that we've grazed their since the grass first grew. Even if we are traveling away from the grass and our homes, we are killed because we can't fly over mountains or swim across seas.
Our existance is not a crime! As gentle grazers, our people have never done anything to invoke the haterid of these mortals. If they smelled of an unnatural taint, we would seek out the source. But it seems as if every lesser race has lost its' mind in unison. Since we do not have the choice to flee, that only leaves us with the need to fight. If humans have moved into our grazing meadows, they have to be pushed back so our people can eat. If the humans are in our watering holes, they have to be forced out so our people can drink. No matter the cost, a place to live must be reclaimed and loved ones protected for the sake of our lives.
Are dragons more worthy of life because of their magic? No, but they eat the live stock and wild game we need to feed our families. Unless the dragons have a taste for human while they are out and about. Then they simply kill of relatives by devouring them instead of slowly starving us to death. Do gryffins have more mastery over creation because of their flight? No, but they descimate our live stock and hunting grounds just as readily as the dragons. They may not eat our loved ones, but they still play a role in starving us. Even when live stock does survive even the Unicorns doom us to extinction by eating the healthier grass and grains and leave our cattle the weeds.
No mystical creature is better than us simply because of magic! No creature has a greater right to life than us! We will show them the worth of our race. For the sake of generations to come, we will make this land a realm of mortals. A safe heaven where the forests are filled with game, the fields are full of grass, and death doesn't decend from the sky. We will reclaim this land for our survival if. All who do not leave willingly will be buried instead!
Premise in a Nutshell: Most of the mystical creators fled because they've lived long enough to know how bad war can get. Unfortunately, the Unicorns are stuck fighting against Mortals who want everything to themselves. The Mortals have started a revolt against the Mystical creatures who used resources so recklessly it left them with the option to fight for what's left or starve. Pick a side and go nuts.
Not Your Typical Unicorn
Setting: This world started out as any typical medieval fantasy world with all its creatures and races. Every magical creature was hunted, from the great and powerful dragons to the most innocent of unicorns. Having the ability to fly, the dragons, gryphons and others fled the world of Man (and elf? or other races?). The unicorns, being prisoners of the earth, could only flee so far until their way was blocked by either shore or mountain. Once the horned horses were cornered, something happened that made them change. No one is quite sure what. Some say a wizard transformed them. Others say that a unicorn killed a man defending itself and that all its pure magic turned against the creature causing it to change. There are no more innocent unicorns. For one reason or another, they have all become carnivorous monsters and are feared more than wolves or bears. Wolves and bears are dangerous but they lack the intelligence of a unicorn.
Premise: Not quite sure how to play this one out. First thought is a war between man and unicorns with played characters on both sides.
I replaced Humans with Mortals in case someone whats to be a UNnicorn slaying troll. A mortal is simply a race that cannot use magic even if that race happens to fly. So if you are a mortal Elf you can't use magic even if every other rp on the planet makes elves magic masters.
I also made the unicorns sentient so the Unicorn side can communicate by typing more than "nay" and "snort".
I'm also sick of rps that need a definite bad guy. The Unicorns are full of themselves becuase they have magic and the "lesser races" are stuck swinging around swords. They can't even begin to imagine a world when they would do much more than ignore the existance of mortals as they go about their business. Moratals are so sick of being outdone by the mysticals that they become jealous and greedy. They can't be satistifed with a piece of the pie, they want the entire bakery now.
Also, no one would feel like they have to be a Unicorn to be bad or they would have to be mortal to be good. You also don't have to be loyal to your race. You can be a mortal who thinks the mysticals could learn to share with us. You can be a Unicorn who realizes the unicorns have been vain and should try to talk things out with the humans. You can even be a maverick who is sick of both sides and wants everyone to die. But I'm pretty sure that choice will have you killed by every other player.
As I said in purple, We could pick a side and go nuts.
Also, if a troll did pop in to mess things up, it would be fairly easy to rp the troll away with this much flexibility. I'm a human mage in my LARP and a tuaren hunter in my MMORPG. It's about time I rolled something insane like a Unicorn Necromancer.
Me: "You killed my family" *cast spell* "Now my family will kill you!"
