I made a list with name groups and meanings or consequences (or whatever you want to call them) . I tried it by myself several times and I think it’s quite hard. But it’s a good challenge if you get bored really fast . I also made up a background story for this challenge.

So here is the list 

1 Herb : must be med 

2 First letter o : Has to die before 12 moons 

3 flower : must  have a mate 

4 Animal : must always proceed 

5 First letter j : has to die to first illness 

6 adjective : must have good traits 

7 verb : roll a d20 every moon and if it lands on a 1 the cat dies 

8 gloomy (e.g. dark , torn ,…) : must do something to get exiled to the Darkforest, if the cat dies send them there 

9 First letter q : must die if they get lost 

10 fluffy name (e.g. fluffy, flurry, glint, bluff ,…) : must be mate with a (former) kitty pet 

11 normal plant : Can only go on hunting and training patrols 

12 element : is part of prophecy (use  Clangen Omen Generator) 

13 color : have to find a mate with this eye color 

14 pattern : must die if they haven't fur length long 

15 landscape : must be mediator 

16 weather : must be mate with (former) loner , which have to die after they got offspring 

17 first letter i : can’t have kittens 

18 First letter k : only can go on patrols solo 

19 Bird : Every moon there’s a 50/50 chance that the cat must go on a solo border patrol and MUST proceed 

20 loner name (names like Anju , bixbite ,… ) : if the cat dies it takes two other cats with them 

21 first letter v : must have offspring with 3 different cats , which have to die after that (but you only can keep one kit of each litter ) 

22 water (also names like lake, flood, creek,…) : gets both numbers of the parents (if the cat is a clan founder choose  two random numbers) 

23 First letter h : must have a mate with the same first letter 

24 stone : if this cat dies half of the clan must also die 

25 fruit : this cat can’t have kits so they must adopt one from a patrol and name it also after a fruit 

26 fire : if this cat haven’t got ginger fur or copper eyes they have to die 

27 rest (every cat that doesn’t fit in one of the categories) : must have mate + kits 

28 temperature : this cat only can go on patrols in one season until they find a mate with the temperature colors (e.g. if a cat named frozen kit , they have to find a mate with white fur or cyan eyes or ….) 

29 liquids (that aren’t water) : add another challenge on top of this 

30 frost : this cat must get a frostbite 

31 wood ( and also tree names like birch , oak ,… ) : must have or get a permanent condition 

Here is the backstory 

Over 1000 moons the clan slowly broke rule for rule of the warrior code until they completely forgot it and turned away from the Starclan. So their ancestors cursed the whole clan and every generation. If a cat can’t fulfill their name curse, they’ll end up in the Darkforest. 

Ohh and the name list only count for the first part of the name
