Rule 1. Follow the naming laws.
A small but important rule, while its not officially put in the Warrior Code, however the clans do normally follow it, just like the other rules. Except Skyclan in some cases, So what's this rule?
DO NOT. Call your cat...
anything Moon. (Moonfur, Brightmoon etc)
Anything star UNLESS a leader. (Starwing, etc)
Anything that is a human item. (Hammerclaw, Bulletwind, Silverbarrel etc)
Clan words at the front of their names. (Unless that is a founder of a brand new clan, it shouldn't be there). (Thunderfoot. Windstorm Skywing)
When this has been broken: Windflight, Moonflower Skyheart. mistakes Vicky apologised for. Only exception to this was Skywatcher.
Quote from one of the Erin's about the moon name "...So the moon has significance, mystery, beauty, but not actual power, if you see what I mean. Early on, we decided that the name "moon" shouldn't be used by Clan cats not because it would insult StarClan, but because it would imply that a particular cat had more beauty and significance than its Clanmates. In fact (Warriors trivia coming up!) Bluestar was originally called Moonstone! "
What they said about human names/items in the main clans. "Cat names are meant to only come from natural sources, and are meant to only consist of words that a wild cat would know. "
Fun fact! Tigerclaw/stars original name was Hammerclaw! But Vicky changed it because wild cats don't understand our Two-leg things.
Use natural colours for names. (Grayspots, Blackpelt, Tawnyfur etc)
Use types of trees/plants for names. (Willowtail, Timberclaw etc.)
Name your warrior after landmarks and food. (Milksplash, Shrewnose, Runningcreek etc)
Avoid chucking random words together to make a name. Apparently this doesn't have to be followed in Skyclan. I mean Bouncefire? Harveymoon? Billystorm? Yes I understand the kittypets wanted to keep their names, they still sound stupid however. (Good examples of these failed names are Waterblaze, Snailwing, Firecreek, Hutchwhisker, Blacklight etc)
If you are aiming to be original with names, but not sure on what, look up birds, look up tree types, anything that belongs to nature! Or just ask me, I'd be fine helping! (Elmpelt, Cedartail, Lilypatch Thriftpetal Ducknose.)
Rule 2. USE THE WARRIOR CODE!
Probably the most obvious, but mostly ignored rule. Why? I have no idea. For those hazy on all the official rules of the warrior code, I shall list them right now for you!
1. Defend your own clan with your life. You are allowed Friendships with other clans, but your main loyalty must be to your clan.
2. Do not hunt on another territory, or trespass.
3. All Elders, Queens Medicine-cat and kits are always fed before the Leader, Deputy, Warriors or Apprentices. Only exceptions are if the warrior or apprentice leader or deputy is ill. Or if they have permission from the leader or deputy.
4. prey is killed for food, show thanks to Starclan/ancestors by burying the remains when you are finished.
5. A kitten must be six moons/months before being apprenticed.
6. New warriors will sit vigil the first night they are made a warrior.
7. A cat can't be a deputy unless having mentored one Apprentice
8. The deputy of the clan becomes leader once leader is dead, or retired.
9. Once there is a new leader, or the old deputy is deceased/gone. The leader must choose a new deputy before moon-high
10. A gathering is held every full moon, there is no fighting during this time, as a full moon is the sign of a truce.
11. Boundaries are patrolled daily
12. No warrior must ignore a kit in danger, pain or lost, even if it is from another clan.
13. You listen to the leader of your clan like it is the rules of the warrior code. In other words, not to be ignored
14. A warrior does not need to kill to win a fight, unless a last resort or the rogue/loner is dangerous to the whole clan.
15. A warrior despises and rejects the soft life of a kittypet.
And the additional rules!
No gender medicine cat can take a mate or kits. Only exception is if they had kits, and they died (most of the time) or if they had a mate, but the mate left the clan, hates them stops being their mate, or their mate dies.
Kits must stay in camp unless apprenticed, or hunt unless given permission and under strict super vision by the deputy or leader.
The safety of the clan is more important than one single warrior, mate or not.
Clans can not unite to drive out other clans.
Clans can not force another clan to share territory.
Clans can not attack a patrol that is on a mission that is agreed on by all leaders.
I understand that sometimes you must break these rules to make your story more interesting or liven it up. However I often find a clan barely listening to the code is boring and over done, a truly dedicated clan to the code would be an interesting read if you went into detail why. And if your going to make a "bad" character, make him a saint. Seriously. Them following the code savagely to death then turning if the code might be hurt. Hence why Hollyleaf was a good character!Or make the "bad" character a believable character, while its possible he could just break the code for fun, actually go into depth as to WHY he hates the code. No being half clan doesn't count. Or a medicine cat. Nice try though. Also don't use the boring abused child route. Or heartbroken, you just make them like Ashfur,
Rule 3. TRY
Be it maybe you don't have much time to write, or "you don't want to write anything serious." I see a lot of pretty poor fan fiction about. It recycling either these story lines OVER and OVER.
A kit (be it tom or she cat) receives a prophecy when it is born, telling them either about their great destiny, or great evil, they grow up and their parents/sibling/best friend die, so then the tom/she-cat become the clans best warrior/leader of (Insert area and clan here)
A blind cat becomes a warrior (which has been proven impossible) and then slowly deputy and leader. Has a 'hard life' of being sympathized with, not taken seriously and worst of all, laughed at. LEGASP.
Your cat gets super powers from some prophecy just like the Three in the official series. They rebel against the code, their family, clan because 'their power is too great for anyone to understand' either they go bat-shit, or do their destiny shit and are permanently better then every other cat. The end.
A cat always works hard in hopes to get the mate he/she wants. When they don't they become Bat shit insane. Then kill their enemy/once wanted mate/someone. And continue to live with their angst, hating everyone around them.
Or a combination of all the above. Seriously all because your busy Doesn't mean you can't think outside the box! Take me for example, I'm busy with many things, yet I still sit here and am working hard on the first original warrior cat story there will be in a long time. And actually it isn't about my OC's (well one is, but she isn't a copy of anyone nor is she super powered-awesome-named or abused-sad-depressed psychopath.) And its set in the four clans around the lake. Maybe you should stick around and learn a few things and tips! I'm often about to help so if you actually sat back and said "Hmm what could I do to make this seem better" you can ask me. Seriously I like helping people that's why I wrote this.
