Many years later i'm done x.x Instead of writing my research report like a good student i've been drawing this for a couple of days.
Here are Swiftstar's grandchildren Larkwing, Hawkstone and Crowspark. Their parents are Nightfeather and Iceclaw.

Crowspark is a bit of a wayward kit and wanders around their territory quite alot on her own. She is a fierce and hotheaded fighter and defends Lightningclans borders thoroughly; she is a very confident fighter and isnt afraid to back up her words with claws. As an apprentice she attempted to chase a fox out of the territory on her own after it had caused trouble with the clan. Because of her reckless behaviour she doesnt get on very well with Hawkstone. (Soldier)

Hawkstone is a stubborn defender of the warrior code and follows it to the letter, leading him to disapprove of Crowsparks independent and occasionally dangerous behaviour. He is strategic and sometimes pompous, and often comes across as strict and cold, but does have a playful streak when the mood strikes him. He has a habit of interrupting more senior warriors if something important is happening and he believes he has a better solution to theirs. (King)

Larkwing is the smallest of their litter and is a lot quieter than her littermates. She was timid and shy as a kit and apprentice, but is more mature than her siblings and is very good at soothing ruffled fur. She frequently settles disputes between Hawkstone and Crowspark and is exasperated with their frequent bickering but prefers it to their silences. She is very fair and loyal and is becoming more confident. (Poet)
