I was gonna start a topic about the exact same thing! LOL Oh well. But here are some suggestions, add mortal parent and abilities in the character thing, I'll add it to mine but everyone else doesn't have to, it's just a suggestion.
This starts when your character is still at your house and is going to go to camp half blood, not they're already in camp half blood, right? 'Cause if it's not then there's one less adventure for all of us. Anyways, here's my character.
Name: Eleanor Humynber (I made just up the last name, if it turns out to mean something bad in another language or something then I'm really sorry, I didn't mean it, I just made it up)
Age: 13 1/2
Roman/Greek God/Goddess Parent+ Cabin Job: (Greek) Iris, cabin job taking care of the pegasi, probably? IDK
Mortal parent (full name) : Neil Humynber
Appearance: A bit short black hair but long enough to be braided on one side, brown eyes, likes to smile, a bit tall
Personality: honest, smart, generous, rude, cowardly and untidy
Abilities: strong (you know the can carry really heavy stuff and do a lot of pull ups kind of strong), flexible (you know the touch your head with your toes, lick your elbow kind of flexible), fast (as in really fast, like a cheetah or something) and Iris powers I guess, controls light and stuff
