From left to right-Lalaith, Taure, Riel, and Kano. I estimate their (apparent) ages to be 12, 10, 7, and 5.

Lalaith is the oldest and is also the tomboy of the family. Her actions are, on average, completely impulsive. If it sounds exciting, she'll more than likely do it no questions asked. Unfortunatly, a lot of her antics are dangerous. I predict a lot of heart attacks on her parents' end XD And many, many injuries on hers. But she doesn't seem to care. She's very athletic and hates staying still for more than a minute. She's also extremely flexible and has an addiction to chocolate. She comes off as fearless, but is secretly terrified of spiders and stinging insects. Wants to explore the entire world one day. She also has the accidental habit to beat up boys she's interested in. However, despite being a tomboy she is still completely capable of enjoying more feminine activites like tea parties with her younger sister. Provided she gets to share all her adventure stories. And they pretend that they're on a pirate ship holding said tea party. She's overly trusting towards others and tends to push off problems as much as she can. Loves to help others.

Taure: http://eternalspirit1991.deviantart.com/art/Taure-134523655 . Except that we've added that he is a pyro. :>

Riel is a girly girl. She enjoys staying inside and playing games like pretending she's a princess and dress up. She also likes daydreaming and occassionally drawing things. She's creative, but quiet. Except when things don't quite go her way. Then she puts up a huge fuss. She has a soft spot for animals of any kind and is always bringing home strays the few times she is outdoors. Then hides them in her room and secretly cares for them :> She likes sewing and has sort of forced the talent upon everyone in the family whether they want to learn or not...

Kano: http://eternalspirit1991.deviantart.com/art/Kano-3-134746199 Oblivious like his dad. XD
