Certainly on all three accounts(uniforms, ping list, and our characters being friends)!

I'll have to give the uniforms a bit more thought. Such as what boys and girls should wear and the changes to a student's attire for the different seasons.

Name(full): Katie Snow
Age:15
Group: izota
Personality: shy, helpful

Creature:
Family:if anyone would like someone can be my brother
Background:I can't really think of one...
Boyfriend/crush:(open)

Alright I have an idea for the uniforms. Tell me what you think about it and the colors.

The girls have to wear,
1. a white-collared shirt with long sleeves, or a white collared shirt with short sleeves
2. a knee-length skirt the color of their group(I'll explain what I think the colors should be later in the post)
3. white socks of any length
4. brown loafers(it's a type of preppy shoe that some people wear to school)
5. scholarly jackets are optional, but must be the color of your group(winter is the one exception)


The boys have to wear,
1. a white-collared shirt with long sleeves, or a white collared shirt with short sleeves
2. dress pants the color of their group
3. ankle or mid-calf length socks
4. brown loafers
5. scholarly jackets are optional, but must be the color of your group(winter is the one exception)


Now it is time for me to explain what I think the colors of the different groups should be.

Haizean: white
Urana: deep blues or blue-green colors
Lurr: greens or browns
Sutea: reds or oranges
Izota : an extremely light blue
Soinau: silver or grays
Argi: light yellows
Tzala: black or a very dark purple
Adimen: purples, lighter purples, or certain deep red-violets

Name: Sylver Lunydia
Age: 15
Group: Tzala
Personality: Quiet, shy, very affectionate and loving once she gets to know people. She's selectively mute, but she never speaks and can communicate with others by using Morse code, and spelling out words by drawing, but prefers to use Morse. Though Sylver appears fairly intimidating, she's a sweetheart and is very protective of her friends when she has them.
Appearance: Golden blonde hair, crystal blue eyes.
Creature: Ambrosia
Background: Her mother and father are both magicians, her mother and father are Tzala like her, but her farher's side is a complete magical mix. Her cousin Lolani is a half blooded magician Haizean, her mother's side is fully tzala, but on her father's side she has two aunts and three uncles which are almost all different.
Crush/Girlfriend or boyfriend: She has a crush on an Argi named Rhys.

Accepted!

Accepted!

Quick question: are we allowed to have more than one character or no? (Or can we use other characters as npcs)

Yes, I agree with the uniforms for both boys and girls. Here are my specific color ideas (based off yours).

Haizean: cream
Urana: teal
Lurr: tan
Sutea: vermilion
Izota : periwinkle
Soinau: silver
Argi: light yellow
Tzala: black
Adimen: red-violet

You can only make one, and almost all slots are closed. However, you can create other characters that we will interact with, like secondary characters. As long as they're not main characters.

Okay, cool
